  "details": "Advanced File System turns Drupal\u0027s file storage into a manageable, observable and maintainable subsystem.\n\nThe 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.\n\nThe vulnerability is mitigated by the fact that `advanced_filesystem_backup` module must be enabled.",
