The SigmaForms Pro – AI Generated Forms plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_submission_files function in all versions up to, and including, 1.4.11. 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). The malicious path traversal URL is submitted via form upload field and stored in the database, with deletion triggered when an administrator deletes the submission record from the admin panel.

The SigmaForms Pro – AI Generated Forms plugin for WordPress contains a critical arbitrary file deletion vulnerability in the delete_submission_files function. All versions up to and including 1.4.11 are affected. Unauthenticated attackers can exploit insufficient file path validation to delete arbitrary files on the server. The attack vector involves submitting a malicious path traversal URL via a form upload field, which is stored in the database. Deletion is triggered when an administrator removes the submission record from the admin panel. This can lead to remote code execution, for example by deleting wp-config.php, which may destabilize the WordPress installation and open the door to further exploitation. No authentication is required for the initial injection phase, making this accessible to a wide range of attackers.
