CVE-2026-84702: Path traversal vulnerability

facefusion through 3.6.1 fails to normalize job identifiers in get_job_file_name, allowing attackers to write files outside the jobs directory. Attackers can supply traversal sequences in the job identifier parameter through the unauthenticated HTTP API to create files at arbitrary locations.
