Frontend Admin by DynamiApps <= 3.29.12 - Unauthenticated Arbitrary File Deletion via Path Traversal via custom_directory_name Merge Tag
The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the move_folders function in all versions up to, and including, 3.29.12. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This is exploitable without authentication when a form is configured with public visibility (who_can_see='all'), as the required nonce is publicly obtainable from the rendered form.
