What is CVE-2026-13207?
CVE-2026-13207 is a high-severity authentication bypass vulnerability in Frangoteam FUXA SCADA/HMI, published on 30 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
FUXA versions 1.3.1 and prior contain an authentication bypass vulnerability via dot-segment path normalization in the REST API. The API router fails to normalize dot-segment sequences before applying authentication middleware, allowing unauthenticated requests to access protected endpoints by prefixing paths with dot-segments such as /api/./users, /api/./roles, and /api/project/../users. These requests bypass authentication checks and return sensitive user and role data without credentials.
Weakness: CWE-290
