Name of the Vulnerable Software and Affected Versions FUXA versions prior to 1.3.2

Description An authentication bypass exists in the REST API due to improper dot-segment path normalization. The API router does not normalize dot-segment sequences before the authentication middleware is applied. This allows unauthenticated users to access protected endpoints by prefixing paths with dot-segments, such as '/api/./users', '/api/./roles', and '/api/project/../users', resulting in the unauthorized disclosure of sensitive user and role data.

Recommendations Update FUXA to version 1.3.2 or later.
