What is CVE-2025-69985?

The FUXA application prior to version 1.2.8 suffers from an Authentication Bypass vulnerability that permits remote code execution. This flaw resides in the server/api/jwt-helper.js middleware, where the system incorrectly trusts the HTTP 'Referer' header to validate internal requests. An attacker, without authentication, can exploit this by spoofing the Referer header to align with the server's host. Once successful, the attacker gains unauthorized access to the sensitive /api/runscript endpoint, enabling the execution of arbitrary Node.js code on the server.
