CVE-2026-84702
facefusion through 3.6.1 fails to normalize job identifiers in get_job_file_name, allowing attackers to write files outside the jobs directory.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.56%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
