DescriptionCVE.org

A vulnerability was detected in ComfyUI up to 0.13.0. This impacts the function get_model_preview of the file app/model_manager.py of the component Model Preview Endpoint. The manipulation results in path traversal. The attack may be launched remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

Vulnerability AssessmentAI

Exploitation Exploitation requires valid authentication to ComfyUI (PR:L indicates authenticated user or lower-privileged account access). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment CVSS score of 4.3 with network attack vector and low complexity indicates a moderate baseline risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated user with a valid ComfyUI account crafts a malicious request to the Model Preview Endpoint, injecting a path traversal payload such as '../../../etc/passwd' or similar sequences into the model preview parameter. The endpoint, failing to sanitize the path, resolves the traversal sequence and returns the contents of the target file. …
Remediation No vendor-released patch has been identified at time of analysis, and the vendor did not respond to early disclosure. … Detailed patch versions, workarounds, and compensating controls in full report.
