CVE-2026-6589 Details
Description
A security vulnerability has been detected in ComfyUI up to 0.13.0. This affects the function create_origin_only_middleware of the file server.py. The manipulation leads to cross-site request forgery. The attack may be initiated remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A cross-site request forgery (CSRF) vulnerability has been identified in ComfyUI versions through 0.13.0. The issue arises in the 'create_origin_only_middleware' function within 'server.py', where the middleware fails to properly validate the 'Origin' header. This flaw allows remote attackers to bypass CSRF protections and exploit the vulnerability. The lack of authentication in ComfyUI further exacerbates the issue, as it leaves the application open to unauthorized access via the victim's browser.
