Lifecycle Timeline
4DescriptionCVE.org
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.
AnalysisAI
Path traversal in facefusion's HTTP job management API allows unauthenticated remote attackers to write files at arbitrary server locations, escaping the intended jobs directory sandbox. Versions through 3.6.1 are affected; the root cause is failure to normalize job identifiers in get_job_file_name before constructing file paths. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The facefusion HTTP job management API must be network-accessible; the CVSS vector confirms no authentication is required (PR:N) and no attack complexity or special prerequisites apply (AC:L, AT:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VI:H) accurately captures the core risk profile: unauthenticated, low-complexity, network-reachable arbitrary file write with no preconditions. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade facefusion to version 3.7.0 or later, which contains the path normalization fix delivered in commit a2cbfd73b10191e51ed2eb1e83c19121153e0a22; the patched release is available at https://github.com/facefusion/facefusion/releases/tag/3.7.0. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all systems running facefusion versions through 3.6.1 and immediately restrict network access to the HTTP API if currently internet-exposed; monitor API logs for path traversal attempts using patterns like '../' or URL-encoded equivalents. …
