Under some circumstances, the Drupal core JSON:API module does not properly restrict access to certain content, which may result in unintended access bypass.
Sites that do not have the JSON:API module enabled are not affected.
This advisory is not covered by Drupal Steward.
Solution:Install the latest version:
Versions of Drupal 8 prior to 8.9.x and versions of Drupal 9 prior to 9.1.x are end-of-life and do not receive security coverage.
Drupal 7 core does not include the JSON:API module and therefore is not affected.
Reported By: Fixed By:The QuickEdit module does not properly check access to fields in some circumstances, which can lead to unintended disclosure of field data.
Sites are only affected if the QuickEdit module (which comes with the Standard profile) is installed.
This advisory is not covered by Drupal Steward.
Solution:Install the latest version:
Versions of Drupal 8 prior to 8.9.x and versions of Drupal 9 prior to 9.1.x are end-of-life and do not receive security coverage.
Drupal 7 core does not include the QuickEdit module and therefore is not affected.
Uninstalling the QuickEdit module will also mitigate the vulnerability. Site owners may wish to consider this option as the QuickEdit module will be removed from core in Drupal 10.
Reported By: Fixed By:Drupal's JSON:API and REST/File modules allow file uploads through their HTTP APIs. The modules do not correctly run all file validation, which causes an access bypass vulnerability. An attacker might be able to upload files that bypass the file validation process implemented by modules on the site.
This vulnerability is mitigated by three factors:
This advisory is not covered by Drupal Steward.

Drupal 7 core is not affected.
Reported By: Fixed By:The QuickEdit module does not properly validate access to routes, which could allow cross-site request forgery under some circumstances and lead to possible data integrity issues.
Sites are only affected if the QuickEdit module (which comes with the Standard profile) is installed. Removing the "access in-place editing" permission from untrusted users will not fully mitigate the vulnerability.

Reported By: Fixed By:The Drupal core Media module allows embedding internal and external media in content fields. In certain circumstances, the filter could allow an unprivileged user to inject HTML into a page when it is accessed by a trusted user with permission to embed media. In some cases, this could lead to cross-site scripting.

Solution:Install the latest version:
Versions of Drupal 8 prior to 8.9.x and versions of Drupal 9 prior to 9.1.x are end-of-life and do not receive security coverage.
Drupal 7 core is not affected.
Reported By: Fixed By:The Drupal project uses the CKEditor, library for WYSIWYG editing. CKEditor has released a security update that impacts Drupal.
Vulnerabilities are possible if Drupal is configured to allow use of the CKEditor library for WYSIWYG editing. An attacker that can create or edit content (even without access to CKEditor themselves) may be able to exploit one or more Cross-Site Scripting (XSS) vulnerabilities to target users with access to the WYSIWYG CKEditor, including site admins with privileged access.
For more information, see CKEditor's announcement of the release.

Solution:Install the latest version:
Versions of Drupal 8 prior to 8.9.x and versions of Drupal 9 prior to 9.1.x are end-of-life and do not receive security coverage.
Drupal 7 core is not affected, although Drupal 7, 8, and 9 site owners should review their site following the protocol for managing external libraries and plugins previously suggested by the Drupal Security Team, as contributed projects may use additional CKEditor plugins not packaged in Drupal core.
Reported By: Fixed By:The Drupal project uses the pear Archive_Tar library, which has released a security update that impacts Drupal.
The vulnerability is mitigated by the fact that Drupal core's use of the Archive_Tar library is not vulnerable, as it does not permit symlinks.
Exploitation may be possible if contrib or custom code uses the library to extract tar archives (for example .tar, .tar.gz, .bz2, or .tlz) which come from a potentially untrusted source.
