drupal/advanced_filesystem is vulnerable to Cross-Site Request Forgery (CSRF)
48
Medium Risk
This Affects:
drupal/advanced_filesystemTL;DR
The Advanced Filesystem module's Backup submodule exposes state-changing backup routes without a CSRF token. An attacker can trick an authenticated user who can administer backups into unintentionally running or queueing a backup, processing the backup queue, or cancelling, deleting, or force-resetting a backup run. This applies only when the advanced_filesystem_backup submodule is enabled. Version 1.0.28 requires a CSRF token on the affected routes.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and have the Advanced Filesystem Backup submodule (advanced_filesystem_backup) enabled.
