InvokeAI before 6.13.7 contains an unauthenticated directory enumeration vulnerability in the GET /api/v2/models/scan_folder endpoint that accepts attacker-controlled scan_path parameters. Unauthenticated attackers can recursively enumerate arbitrary server filesystem directories and use HTTP response codes to determine file existence and readability, bypassing multi-user mode access controls.
