CVE-2026-107262
Description
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.
