CVE-2026-25951: FUXA Affected by a Path Traversal Sanitization Bypass

A flaw in the path sanitization logic allows an authenticated attacker with administrative privileges to bypass directory traversal protections. By using nested traversal sequences (e.g., ….//), an attacker can write arbitrary files to the server filesystem, including sensitive directories like runtime/scripts. This leads to Remote Code Execution (RCE) when the server reloads the malicious scripts. It is a new vulnerability a patch bypass for the sanitization in the last release .
