Executive brief
ComfyUI-Manager is an extension system for the ComfyUI AI image processing application. Versions prior to 3.38 stored configuration and critical data files in a location accessible via the web interface, allowing remote attackers to view, modify, or exfiltrate sensitive application settings and user data without authentication.
Technical details
The vulnerability is an unprotected alternate channel (CWE-420) where ComfyUI-Manager stored its files in a web-accessible directory without proper access controls. The application failed to restrict direct HTTP access to configuration and data files, allowing unauthenticated remote attackers to read and potentially manipulate critical application state. This affects all versions prior to 3.38. The fix involved implementing system user protection APIs and migrating sensitive data to protected locations. The vulnerability is network-reachable and requires no authentication or user interaction.
