CVE-2026-78657
CriticalCVSS 9.8Summary
The SigmaForms Pro – AI Generated Forms plugin for WordPress up to version 1.4.11 is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_submission_files function. Unauthenticated attackers can 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.
Risk Assessment
The risk is critical because an unauthenticated attacker can delete key server files, potentially leading to full compromise of the WordPress site.
Recommendation
Immediately update the plugin to the latest patched version. Additionally, restrict access to the admin panel and monitor logs for suspicious activity.
