description

ComfyUI-Easy-Use 1.3.6 is affected by a path traversal flaw in its preview-saving functionality. An unauthenticated attacker who can reach the ComfyUI server may replace custom-node code, which can run with the ComfyUI process privileges after a restart.

mitigation

Do not expose the ComfyUI server to untrusted networks; restrict access to trusted users and networks and block untrusted uploads. Review custom-node files and restart only after verifying their integrity.
