CVE-2024-12882Public exploitNetwork attack vector

Unauthorized resource access via unvalidated model URL

Published Mar 20, 2025 · Updated Mar 20, 2025

SSRF in Comfy Org ComfyUI 0.2.4 allows remote attackers to read unauthorized web resources through the victim server. The /internal/models/download handler accepts an unvalidated URL, fetches it with the server's aiohttp client, saves the response under an attacker-chosen model path, and /view returns the stored content. The attack requires HTTP access to ComfyUI, which binds to 127.0.0.1 by default; an exposed instance lets unauthenticated callers send requests with the server's network reach and credentials.
