## Details

* Security - Prevent params body from overriding validated occ command: [#41577](https://github.com/owncloud/core/pull/41577)

   OccController validated the URL-path command against an allowlist but then
   merged it with user-supplied params via array_merge, allowing a command key in
   the request body to overwrite the validated value. An authenticated caller with
   the updater secret could use this to execute any occ command regardless of the
   allowlist. The params array is now stripped of any command key before the merge.

   https://github.com/owncloud/core/pull/41577

* Security - Remove plaintext federation auth token from error log: [#41578](https://github.com/owncloud/core/pull/41578)

   When getSharedSecret received an invalid token it logged both the submitted
   value and the expected valid token in plaintext. Since the endpoint is public,
   any unauthenticated caller could trigger this log entry at will for any trusted
   server URL, exposing the valid token to anyone with log-read access.

   A second leak in the same code path has also been closed: the GetSharedSecret
   background job sends the token as a GET query parameter, so on an unexpected
   HTTP response the Guzzle exception - whose message embeds the full request URI
   including &quot;?token=...&quot; - was logged verbatim. Both log sites no longer emit the
   token value.

   https://github.com/owncloud/core/pull/41578

* Security - Replace strcmp token oracle with hash-based comparison in federation: [#41579](https://github.com/owncloud/core/pull/41579)

   The requestSharedSecret endpoint used strcmp() to compare caller-supplied and
   stored federation tokens, returning different HTTP responses based on
   lexicographic ordering. This allowed an unauthenticated attacker to recover the
   stored token via binary search in approximately 96 requests. Tokens are now
   compared by their SHA-256 hashes, removing the plaintext oracle while preserving
   the tiebreaking behaviour.

   https://github.com/owncloud/core/pull/41579

* Security - Restrict unserialize() allowed classes in CommandJob: [#41582](https://github.com/owncloud/core/pull/41582)

   CommandJob::run() called unserialize() without the allowed_classes option on
   data sourced from the oc_jobs database table. An attacker with database write
   access could inject a crafted PHP object payload to trigger gadget chains from
   bundled libraries and achieve remote code execution. Deserialization is now
   restricted to verified ICommand implementations only.

   https://github.com/owncloud/core/pull/41582

* Security - Sanitize storage connection error messages returned to clients: [#41585](https://github.com/owncloud/core/pull/41585)

   The external storage status handler returned raw exception messages including
   Guzzle cURL error details such as resolved IP addresses and port numbers in the
   JSON response. This allowed authenticated users to distinguish connection states
   and map internal network topology. The full exception is now logged server-side
   only; a generic message is returned to the client.

   https://github.com/owncloud/core/pull/41585

* Security - Prevent user enumeration via differential password reset UI: [#41586](https://github.com/owncloud/core/pull/41586)

   The login form showed a &quot;Reset it?&quot; link only when a valid user on a backend
   that supports password changes was detected. LDAP users produced a different
   response than non-existent users, allowing unauthenticated enumeration of
   accounts on those backends. The backend capability check has been removed; the
   reset link is now shown uniformly regardless of user existence or backend type.

   https://github.com/owncloud/core/pull/41586

* Security - Disable group-admin feature by default behind allow_subadmins: [#41634](https://github.com/owncloud/core/pull/41634)

   Disable the subadmin (group-admin) feature by default behind a new
   allow_subadmins system config, as a security risk-mitigation. The feature's code
   path has known security shortcomings; deployments that rely on it can opt back
   in with 'allow_subadmins' =&gt; true in config.php. On upgrade, existing
   group-admin assignments are ignored until an admin sets 'allow_subadmins' =&gt;
   true in config.php.

   https://github.com/owncloud/core/pull/41634

* Security - Do not trust cached binary paths: [#41732](https://github.com/owncloud/core/pull/41732)

   The paths of the helper binaries used to render previews - ffmpeg, avconv and
   AtomicParsley - were cached in the distributed memory cache and used without
   being checked, then interpolated unquoted into the shell commands built from
   them. A cached path is now stored in the host local cache tier only, is
   validated before it is used, and is quoted when the command line is assembled.

   https://github.com/owncloud/core/pull/41732

* Security - Enforce the read permission in the public share preview endpoint: [#41751](https://github.com/owncloud/core/pull/41751)

   The public share preview endpoint resolved the share by token and rendered the
   requested file without consulting the share's permission bitmask. It now returns
   404 when the share does not carry the read permission, which makes it consistent
   with ShareController::downloadShare() and the public WebDAV route.

   https://github.com/owncloud/core/pull/41751

* Security - Confine backend provided user homes to the data directory: [#41752](https://github.com/owncloud/core/pull/41752)

   A user backend can supply a per user home directory - the LDAP backend for
   instance can be configured to read it from a user attribute such as
   homeDirectory. The account sync accepted that value after nothing more than a
   check for a leading slash, so a home pointing at the ownCloud code directory
   turned the user's file listing into read and write access to the application's
   own PHP files. Writing a PHP file into a web reachable location, or modifying
   one of the shipped ones, results in remote code execution. The relative form was
   concatenated onto the data directory without normalization, so a value
   containing &quot;..&quot; escaped it as well.

   A backend provided home is now rejected unless it resolves inside the configured
   datadirectory. Installations that legitimately keep user homes elsewhere, for
   example on a separate NFS mount, can list the permitted base directories in the
   new &quot;user.home_base_dirs&quot; config option. Symlinks are resolved before the
   comparison, so a symlinked data directory keeps working while a symlink inside
   it cannot be used to escape. Every entry in the option has to be an absolute
   path; entries that are not are ignored, because a relative one would be resolved
   against the working directory of whichever process happens to run the check.

   Note that a home is only set when an account has none yet, so accounts that were
   provisioned before this change keep the home already stored for them.

   https://github.com/owncloud/user_ldap/pull/849

* Security - Encode search highlights before they are returned as a DAV property: [#41760](https://github.com/owncloud/core/pull/41760)

   The search-highlights property of the files search REPORT returned the
   elasticsearch highlight fragment unencoded. The fragment is built from file
   content, so a user who shared a crafted file could place arbitrary markup in the
   property value. The property deliberately carries HTML - line breaks are
   substituted with &lt;br/&gt; - so a client rendering it as HTML would execute the
   injected markup.

   The fragment is now HTML-encoded before the line break substitution, which keeps
   the intended &lt;br/&gt; markup intact.

   https://github.com/owncloud/core/pull/41760

* Bugfix - Point documentation help links at the latest server docs: [#5132](https://github.com/owncloud/docs/issues/5132)

   Contextual documentation links (setup checks, help &amp; tips, app info.xml keys)
   were built as /server/&lt;version&gt;/go.php?to=&lt;key&gt; using the running server's
   concrete version, e.g. /server/10.16/. The documentation site publishes the
   current stable release only under /server/latest/, so those links resolved to a
   non-existent version path and 404'd. The version segment now defaults to
   'latest'; callers may still pass an explicit published version.

   https://github.com/owncloud/docs/issues/5132
   https://github.com/owncloud/core/pull/41688

* Bugfix - Normalise trashbin original-location PROPFIND response: [#39337](https://github.com/owncloud/core/issues/39337)

   In certain situations the trashbin original-location in a PROPFIND response
   contained a leading slash. This change ensures that a relative path (without a
   leading slash) is always returned.

   https://github.com/owncloud/core/issues/39337
   https://github.com/owncloud/core/pull/41649

* Bugfix - Add missing space to mail footer signature delimiter: [#41364](https://github.com/owncloud/core/issues/41364)

   We've fixed the signature delimiter in the email footer templates. The delimiter
   on the first line was missing the trailing space required by the signature block
   convention (RFC 3676), so mail clients were unable to recognize and collapse the
   signature. The delimiter is now correctly written as &quot;-- &quot; (dash-dash-space).

   https://github.com/owncloud/core/pull/41617

* Bugfix - Fix htaccess RewriteBase rules blocking API requests by file extension: [#41418](https://github.com/owncloud/core/issues/41418)

   Files whose names end in extensions like .jpg, .png, .svg, .json and others
   could not be marked as favorites or have their tags updated via the files API
   when htaccess.RewriteBase was configured. The .htaccess rules generated by `occ
   maintenance:update:htaccess` used a URI extension check to skip routing through
   index.php, which inadvertently blocked API requests to paths like
   `/apps/files/api/v1/files/photo.jpg`, returning 405 Method Not Allowed.

   The fix replaces the extension-based condition with `RewriteCond
   %{REQUEST_FILENAME} !-f`, which correctly routes virtual API paths through
   index.php while still serving actual static files directly.

   https://github.com/owncloud/core/issues/41418

* Bugfix - Adjust code to avoid PHP8 messages: [#41597](https://github.com/owncloud/core/pull/41597)

   Avoid trying to access array offset on false in the encryption storage wrapper.

   Handle passing null to normalizeUrl in the federation DbHandler.

   https://github.com/owncloud/core/pull/41597

* Bugfix - Support federation between systems in subdirectories: [#41599](https://github.com/owncloud/core/pull/41599)

   If a federated server was installed in a subdirectory like:

   Mydomain.com/cloud

   Then checks to see that the server is up and responding would fail. This problem
   has been corrected.

   https://github.com/owncloud/core/pull/41599

* Bugfix - Remove owncloud.com/federation link from federated cloud settings: [#41608](https://github.com/owncloud/core/pull/41608)

   The &quot;Add to your website&quot; feature in the personal federation settings was
   generating a link to https://owncloud.com/federation# which no longer works
   after owncloud.com was restructured. The federation Cloud ID is now displayed
   directly without linking to the defunct external page.

   https://github.com/owncloud/core/pull/41608

* Bugfix - Fix JS test isolation bugs exposed by Jasmine 5 random test ordering: [#41616](https://github.com/owncloud/core/pull/41616)

   Several JS test specs left shared singleton state dirty between tests, causing
   intermittent failures when Jasmine 5 ran tests in random order. Fixed
   OC._currentMenu leak in fileactionsmenuSpec, stale OCA.Files.fileActions
   reference causing infinite recursion in files_sharing/appSpec, and stale models
   in the OC.SystemTags.collection singleton in systemtagsinfoviewSpec and
   systemtagsinputfieldSpec.

   https://github.com/owncloud/core/pull/41616

* Bugfix - Honor language on anonymous pages: [#41618](https://github.com/owncloud/core/issues/41618)

   Anonymous pages (the login page and the password-protected public share page)
   always rendered in English even when default_language was configured or the
   browser sent a matching Accept-Language header, while authenticated pages were
   translated correctly. The language factory cached the &quot;en&quot; last-resort fallback
   as the per-request language, which then short-circuited every later lookup
   before default_language or Accept-Language could be consulted. The fallback is
   no longer cached, so anonymous pages honor default_language and Accept-Language.

   https://github.com/owncloud/core/issues/41618

* Bugfix - Decrypt versions and trashbin so encryption can be disabled: [#41623](https://github.com/owncloud/core/issues/41623)

   &quot;occ encryption:decrypt-all&quot; only walked the regular &quot;files&quot; folder, leaving the
   &quot;encrypted&quot; flag set on entries in &quot;files_versions&quot; and &quot;files_trashbin&quot;.
   Because &quot;occ encryption:disable&quot; refuses while any file cache row is still
   flagged as encrypted, administrators were left unable to disable encryption even
   though decrypt-all reported success.

   Decrypt-all now also descends into &quot;files_versions&quot; and &quot;files_trashbin&quot;, and
   the disable command now lists the paths that are still flagged as encrypted
   together with a hint on how to clean them up, instead of printing a generic
   message.

   https://github.com/owncloud/core/pull/41624

* Bugfix - Fix user:home:list-dirs and user:home:list-users crashing on PHP 8: [#41630](https://github.com/owncloud/core/issues/41630)

   The occ commands user:home:list-dirs and user:home:list-users --all passed null
   as the search pattern to IUserManager::search() to mean &quot;all users&quot;. On PHP 8
   the null reached Connection::escapeLikeParameter(string $param) and raised a
   TypeError, aborting the command. Both commands now pass the empty string, which
   is the established &quot;match all&quot; sentinel used by every other caller.

   https://github.com/owncloud/core/issues/41630

* Bugfix - Add MIME types for OpenDocument formats: [#41648](https://github.com/owncloud/core/pull/41648)

   Add MIME type mappings for additional OpenDocument formats for file types odc,
   odi, odm, otc, otg, oth, oti, otp, ots and ott.

   Add MIME type aliases for chart and image formats that were currently missing in
   the default mimetypealiases.dist.json file.

   Update mimetypelist.js using ./occ maintenance:mimetype:update-js

   https://github.com/owncloud/core/pull/41648

* Bugfix - Handle deprecated code related to comments app: [#41656](https://github.com/owncloud/core/pull/41656)

   Code paths that caused deprecation warnings in PHP 8 have been corrected.

   https://github.com/owncloud/core/pull/41656

* Bugfix - Hide navigation icon for apps not enabled for the user: [#41717](https://github.com/owncloud/core/issues/41717)

   Apps that were enabled only for a specific group still showed their navigation
   icon in the top-left app menu for every user, including users who were not in
   that group. Clicking the icon then bounced the user back to the Files app. The
   navigation manager now skips apps that are not enabled for the current user,
   mirroring the per-user check already used for the web navigation entry.

   https://github.com/owncloud/core/issues/41717

* Bugfix - Do not crash on malformed translations: [#41720](https://github.com/owncloud/core/issues/41720)

   Changing the language (and any request that rendered a translated string with
   parameters) could return an HTTP 500 error. On PHP 8 vsprintf() throws a
   ValueError instead of returning false when a translation's format specifiers do
   not match the supplied arguments — a common result of translators turning &quot;%s&quot;
   into &quot;% s&quot; or &quot;%S&quot;, or dropping a specifier. OC_L10N_String::__toString() did
   not guard against this, so a single malformed translation string in a shipped
   language file crashed the whole request. Such translations now fall back to the
   untranslated source text so the request still succeeds.

   https://github.com/owncloud/core/issues/41720

* Bugfix - Reject non-numeric avatar crop coordinates: [#41723](https://github.com/owncloud/core/issues/41723)

   Submitting a profile picture crop with empty or non-numeric coordinates hit the
   image cropping code with invalid values. On PHP 8 this raised a TypeError from
   round() and returned an HTTP 500; on PHP 7 it silently produced a broken crop.
   The client sends empty coordinates (crop[x]=&amp;crop[y]=...) whenever the cropper
   failed to produce a selection. postCroppedAvatar now validates that all four
   coordinates are numeric and returns a clean HTTP 400 otherwise, instead of
   crashing.

   https://github.com/owncloud/core/issues/41723
   https://github.com/owncloud/core/pull/41725

* Bugfix - Fix avatar cropper broken by Jcrop 2.0 file rename: [#41723](https://github.com/owncloud/core/issues/41723)

   Uploading a non-square profile picture opened a cropper that immediately failed
   with &quot;$cropperImage.Jcrop is not a function&quot;. Bumping the Jcrop dependency from
   0.9.12 to 2.0.4 renamed its distribution files from js/jquery.Jcrop.js and
   css/jquery.Jcrop.css to js/Jcrop.js and css/Jcrop.css, but the personal profile
   template still referenced the old paths. The script therefore failed to load,
   the plugin never registered on jQuery, and the cropper could not be shown. The
   template now loads the renamed Jcrop assets.

   Original Jcrop PR: https://github.com/owncloud/core/pull/38666

* Bugfix - Rewire legacy ajax routes to extension-free urls: [#41740](https://github.com/owncloud/core/issues/41740)

   The front controller rewrite only forwards a request to index.php when the
   requested path does not exist on disk. A legacy route whose declared url was
   itself a real file - for example /settings/ajax/setlanguage.php - therefore
   never reached the router: the web server executed the script directly, without
   the bootstrap index.php would have performed, and the request died with `Class
   &quot;OC&quot; not found` (HTTP 500). Changing the personal language setting, the share
   dialog e-mail lookup, the trashbin and public link preview thumbnails and the
   Google Drive OAuth entry point were affected.

   Every such route url has lost its .php suffix so that no route url resolves to a
   file on disk any more, and the affected javascript callers now build routed urls
   through OC.generateUrl(). Route names are unchanged, so linkToRoute() callers
   keep working. The legacy .php urls are gone and no alias is provided - an alias
   would re-introduce the very shadowing this change removes. /core/ajax/update.php
   keeps its suffix by design: it bootstraps itself and is excluded from the
   rewrite. Five routes whose include target no longer existed were removed.
   Third-party apps posting to their own shadowed .php route urls need the same
   treatment.

   https://github.com/owncloud/core/pull/41742

* Bugfix - Request legacy ajax endpoints through the front controller: [#41740](https://github.com/owncloud/core/issues/41740)

   The front controller rewrite only forwards a request to index.php when the
   requested path does not exist on disk. Five javascript call sites requested a
   url that was itself a real file, so the web server executed the script directly,
   without the bootstrap index.php would have performed, and the request died with
   a fatal error (HTTP 500): changing the personal language, the share dialog
   e-mail lookup, the Google Drive OAuth entry point, and the trashbin and public
   link preview thumbnails.

   All five now build their url with an explicit /index.php/ prefix so that the
   request no longer matches a file on disk and reaches the router. The prefix has
   to be part of the url literal because OC.generateUrl() omits /index.php when
   mod_rewrite is active, which is how four of the five came to request the
   shadowed url in the first place.

* Change - No longer store auto loader information in any memory cache: [#41376](https://github.com/owncloud/core/pull/41376)

   With composer managing auto loading for a long time this is no longer necessary.

   https://github.com/owncloud/core/pull/41376

* Change - Raise minimum PHP version to 8.3: [#41449](https://github.com/owncloud/core/pull/41449)

   The minimum required PHP version is now 8.3. Numerous PHP 8.x deprecation
   warnings were resolved across the codebase, the mail subsystem was migrated to
   symfony/mailer, the unused ext-apc requirement was dropped, and the PHP version
   check now runs early in lib/base.php.

* Change - Drop command db:convert-type: [#41451](https://github.com/owncloud/core/pull/41451)

   This experimental command is untested and unsupported and therefore removed.

   https://github.com/owncloud/core/pull/41451

* Change - Removed legacy and deprecated code from ownCloud 11: [#41455](https://github.com/owncloud/core/pull/41455)

   The following have been removed:

   * class OC_DB

   * class OC_DB_StatementWrapper

   * class OC_Group_Backend

   * class OC_Group_Database

   * class OC_OCS_Result

   * class \OCP\DB

   * class MDBSchemaWriter

   * interface OC_Group_Interface

   * interface OC_User_Interface

   * method MDB2SchemaManager::getDbStructure()

   * method MDB2SchemaManager::generateChangeScript()

   https://github.com/owncloud/core/pull/41464
   https://github.com/owncloud/core/pull/41468

* Change - Use configurable URL for internet connectivity check: [#41506](https://github.com/owncloud/core/pull/41506)

   Default URL is now configurable and the default is set to an independent
   resource: https://detectportal.firefox.com/success.txt This also provides an
   IPv6 compatible URL.

   https://github.com/owncloud/core/issues/41465
   https://github.com/owncloud/core/pull/41506

* Change - Use phan major version 6 code analysis: [#41650](https://github.com/owncloud/core/pull/41650)

   Now that PHP 7 support has been dropped, we can use the latest release of the
   phan code analyser.

   Patch releases before 6.0.7 had a problem with the function signatures for some
   Redis methods. That was corrected in https://github.com/phan/phan/pull/5546 and
   released in phan version 6.0.7. So that version is required as the minimum here.

   https://github.com/owncloud/core/pull/41650

* Change - Remove msteamsbridge config sample: [#41668](https://github.com/owncloud/core/pull/41668)

   The owncloud/msteamsbridge integration app is being archived and is no longer
   maintained. Its Microsoft Teams Bridge config sample block has been removed from
   config.apps.sample.php so the config-to-docs sync no longer re-adds the
   parameters to the admin documentation.

   https://github.com/owncloud/core/pull/41668

* Change - G2 code-signing verifier and G1 signature sunset: [#41680](https://github.com/owncloud/core/pull/41680)

   We've replaced the app-signature verification with a new G2 code-signing
   verifier that validates the full certificate chain against bundled trust
   anchors, enforces an algorithm allowlist, and checks a fail-closed CRL for
   revocation.

   Existing G1-signed apps continue to verify during the transition. However, all
   G1 signatures stop verifying on 2027-01-01 (the hardcoded sunset at
   2026-12-31T23:59:59Z), regardless of individual certificate expiry. After that
   cutoff, affected apps must be re-signed with a G2 certificate to install or pass
   integrity verification. Administrators running third-party apps signed under G1
   should plan for re-signed releases ahead of that date.

   https://github.com/owncloud/core/pull/41680

* Change - Remove occ integrity:sign-app and integrity:sign-core commands: [#41712](https://github.com/owncloud/core/pull/41712)

   We've removed the occ integrity:sign-app and integrity:sign-core console
   commands along with the signing-only code in the integrity checker
   (createSignatureData, writeAppSignature and writeCoreSignature). Code signing is
   a release and CI concern rather than an operator action performed against a
   running instance, so this code was dead weight in the security-sensitive
   integrity subsystem.

   Integrity verification is unaffected: the integrity:check-app and
   integrity:check-core commands and all signature verification continue to work as
   before.

   https://github.com/owncloud/core/pull/41712

* Change - Remove the caching router: [#41733](https://github.com/owncloud/core/pull/41733)

   Generated urls are no longer stored in the memory cache. Measurement showed
   generating a url to be faster than a cache round trip, so the cache only added a
   place where urls could go stale or be tampered with.

   https://github.com/owncloud/core/pull/41733

* Change - Keep host local caches in the local cache tier: [#41734](https://github.com/owncloud/core/pull/41734)

   The image paths of the active theme and the mimetype id map were stored in the
   distributed memory cache although both are derived from the files and the
   database of a single instance. They now use the host local cache tier and their
   entries expire, so a stale entry is scoped to one node and no longer lives
   forever. The repair step for mimetypes deletes rows from the mimetype table and
   now clears the mimetype cache afterwards, and occ upgrade clears both cache
   tiers instead of only the distributed one.

   https://github.com/owncloud/core/pull/41734

* Change - Cover HTML metacharacters in the username validation allow-list: [#41738](https://github.com/owncloud/core/pull/41738)

   The username allow-list in OC\User\Manager::createUser() already rejects every
   character outside &quot;a-z&quot;, &quot;A-Z&quot;, &quot;0-9&quot; and &quot;+_.@-'&quot;, which blocks HTML and script
   metacharacters from ever reaching a stored username. That behaviour was only
   covered by three generic invalid-character cases, none of which resembled an
   injection payload.

   The invalid-character data provider now also exercises quote, angle-bracket and
   full script-tag payloads, so any future relaxation of the allow-list that would
   let markup into a username fails the test suite instead of passing unnoticed.
   This is test-only coverage; no production behaviour changes.

   https://github.com/owncloud/core/pull/41738

* Change - Expose createLocal() on ICacheFactory: [#41753](https://github.com/owncloud/core/pull/41753)

   The cache factory has always been able to hand out a cache from the host local
   tier, but the method was missing from the public ICacheFactory interface, so
   core had to ask for it defensively and apps had no way to use it at all. It is
   now part of the interface, which lets values that are only meaningful on the
   machine that produced them be kept out of the cache shared between the nodes of
   an installation.

   Note for app developers: a class implementing OCP\ICacheFactory has to declare
   createLocal() from this release on.

   https://github.com/owncloud/core/pull/41753

* Change - Escape group names in the users administration group list: [#41758](https://github.com/owncloud/core/pull/41758)

   The group list in the users administration panel built each list item by
   concatenating the group id and group name into an HTML string, so both values
   were interpreted as markup rather than text. Unlike usernames, group names are
   not restricted to an allow-listed character set - Group\Manager::createGroup()
   only rejects empty and untrimmed names - so a name containing HTML characters
   was not rendered verbatim. Both interpolated values are now passed through
   escapeHTML(), which makes the encoding consistent with the user rows, and the
   behaviour is covered by tests in settings/tests/js/users/groupsSpec.js.

   https://github.com/owncloud/core/pull/41758

* Change - Honour the write hook veto on legacy chunked WebDAV uploads: [#41762](https://github.com/owncloud/core/pull/41762)

   The legacy WebDAV chunked upload path assembled the final file without
   respecting the pre-write hook result, so the filename blacklist that applies to
   ordinary uploads was not enforced for chunked uploads. The chunked assembly now
   aborts when a write hook vetoes the file, matching the non-chunked upload path.

# Changelog for ownCloud Core [10.16.4] (2026-07-29)

The following sections list the changes in ownCloud core 10.16.4 relevant to
ownCloud admins and users.

[10.16.4]: https://github.com/owncloud/core/compare/v10.16.3...v10.16.4

## Summary

* Bugfix - Fix subadmin email change updating caller's address instead of target's: [#41574](https://github.com/owncloud/core/pull/41574)
* Change - Honour the write hook veto on legacy chunked WebDAV uploads: [#41763](https://github.com/owncloud/core/pull/41763)

## Details

* Bugfix - Fix subadmin email change updating caller's address instead of target's: [#41574](https://github.com/owncloud/core/pull/41574)

   The verification token and confirmation link in the subadmin path of
   setMailAddress were associated with the caller's account instead of the target
   user's account. Clicking the confirmation link changed the subadmin's email
   rather than the intended target's email.

   https://github.com/owncloud/core/pull/41574

* Change - Honour the write hook veto on legacy chunked WebDAV uploads: [#41763](https://github.com/owncloud/core/pull/41763)

   The legacy WebDAV chunked upload path assembled the final file without
   respecting the pre-write hook result, so the filename blacklist that applies to
   ordinary uploads was not enforced for chunked uploads. The chunked assembly now
   aborts when a write hook vetoes the file, matching the non-chunked upload path.
