## Technical details

FUXA v1.2.7 contains an unrestricted file upload vulnerability (CWE-434, CWE-306) in the /api/upload API endpoint. The endpoint lacks authentication checks, allowing unauthenticated remote attackers to upload arbitrary files via a direct network request. An attacker can exploit this to overwrite critical system files such as the SQLite user database to escalate privileges to administrator level, or upload malicious scripts to achieve remote code execution. The vulnerability is triggered by sending a POST request to the unprotected endpoint and requires no user interaction or authentication.
