In some situations, the Image module does not correctly check access to image files not stored in the standard public files directory when generating derivative images using the image styles system.

Access to a non-public file is checked only if it is stored in the "private" file system. However, some contributed modules provide additional file systems, or schemes, which may lead to this vulnerability.

This module enables you to create and manage a version of taxonomy based on configuration entities instead of content. This allows the terms, vocabularies, and their structure to be exported, imported, and managed as site configuration.

The module doesn't sufficiently check access for the edit and delete operations. Users with "access content" permission can edit or delete any term. The edit form may expose term data that users could not otherwise see, since there is no term view route by default.

In Drupal 9.4 and higher, drupal/core-recommended allows patch-level vendor updates

The drupal/core-recommended metapackage now allows patch-level updates for Composer dependencies. This means that site owners using drupal/core-recommended can now install most Composer dependency security updates themselves, without needing to wait for an upstream release of Drupal core that updates the affected package.

Drupal uses the third-party Guzzle library for handling HTTP requests and responses to external services. Guzzle has released a security update which does not affect Drupal core, but may affect some contributed projects or custom code on Drupal sites.
