NVD description

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.

    Critical flaw in the FormGent WordPress plugin (CVE-2026-3141, CVSS 9.1): unauthenticated attackers can delete arbitrary files incl. wp-config.php, leading to full site takeover. Versions ≤1.9.2 affected. Update now. A single unauthorised request from the internet can be enough to take over a WordPress website completely – with no login, no password, and without any staff member having to click on anything. That is precisely what a critical vulnerability in the WordPress plugin FormGent, an AI-powered form builder, makes possible. The flaw, identified as CVE-2026-3141, carries a CVSS score of 9.1 out of 10 and allows attackers to delete arbitrary files on the server – in the worst case the central configuration file wp-config.php. If this is removed, WordPress believes it has been freshly installed, and an attacker can link the site to their own database and make themselves an administrator. If you are running FormGent in a version up to and including 1.9.2, you should act now. A security update is already available. We explain exactly what happened, how to check whether your site is affected, and what specific steps you need to take. #WordPress #CyberSecurity https://shieldgaps.com/en/news/formgent-plugin-critical-flaw-allows-site-takeover-cve-2026-3141-173
