CVE-2026-78657

SigmaForms Pro <= 1.4.11 - Unauthenticated Arbitrary File Deletion via Path Traversal in File Upload Field

Published Sep 2, 2026 CVSS 3.1 · 9.8 Critical EPSS 1.0% KEV · Not listed
Description
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.
