CVE-2026-13207
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.
