CVE-2026-3141: Wpwax Formgent – Next-Gen Ai Form Builder For WordPress With Multi-Step, Quizzes, Payments & More

Critical severity, CVSS 9.1. EPSS: 0.9% chance of exploitation in the next 30 days.

The FormGent plugin for WordPress is vulnerable to unauthorized arbitrary file deletion due to a missing capability check on the /wp-json/formgent/responses/attachments REST API endpoint in all versions up to, and including, 1.9.2 This is due to the REST API route being registered without any authentication middleware in routes/rest/api.php. This makes it possible for unauthenticated attackers to delete arbitrary files within the formgent uploads directory. Additionally, on Linux servers where the wp-content/uploads/formgent directory does not yet exist (the default state after plugin installation), the path traversal protection can be bypassed, enabling deletion of arbitrary files including wp-config.php which can lead to complete site takeover via a fresh WordPress installation.

Affected products

• Wpwax Formgent – Next-Gen Ai Form Builder For WordPress With Multi-Step, Quizzes, Payments & More: up to and including 1.9.2
