    DRUPAL-CONTRIB-2026-217

    Published: 7 Oct 2026Last Modified: 7 Oct 2026

    Summary:

    Details: Advanced File System turns Drupal's file storage into a manageable, observable and maintainable subsystem. The Advanced Filesystem: Backup submodule does not sufficiently validate certain requests. This may allow an attacker to trick an authenticated user into performing unintended actions through a Cross-Site Request Forgery (CSRF) vulnerability. The vulnerability is mitigated by the fact that `advanced_filesystem_backup` module must be enabled.
