CVE-2026-78657 Details
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.
A vulnerability exists in the SigmaForms Pro – AI Generated Forms plugin for WordPress, in all versions through 1.4.11. The issue arises from inadequate validation of file paths in the delete_submission_files function, allowing unauthenticated attackers to delete arbitrary files on the server. This vulnerability could lead to remote code execution if a critical file, such as wp-config.php, is deleted. The exploitation involves uploading a malicious path traversal URL through a form upload field, which is then stored in the database. The deletion is triggered when an administrator removes the corresponding submission record from the admin panel.
Users are advised to update the SigmaForms Pro WordPress plugin to version 1.4.12 or a newer patched version.
