WordPress · Sigmaforms-Pro · CVE-2026-78657
**Name of the Vulnerable Software and Affected Versions**
SigmaForms Pro – AI Generated Forms versions prior to 1.4.12
**Description**
Insufficient file path validation in the `delete submission files()` function allows unauthenticated attackers to delete arbitrary files on the server. This is achieved by submitting a malicious path traversal URL via a form upload field, which is then stored in the database. The deletion is triggered when an administrator removes the submission record from the admin panel. Deleting critical files, such as `wp-config.php`, can lead to remote code execution.
**Recommendations**
Update SigmaForms Pro – AI Generated Forms to version 1.4.12 or later.
As a temporary mitigation, restrict the use of the `delete submission files()` function until the update is applied.
