A CSRF vulnerability exists in comfyanonymous/comfyui versions up to v0.2.2. This vulnerability allows attackers to host malicious websites that, when visited by authenticated ComfyUI users, can perform arbitrary API requests on behalf of the user. This can be exploited to perform actions such as uploading arbitrary files via the /upload/image endpoint. The lack of CSRF protections on API endpoints like /upload/image, /prompt, and /history leaves users vulnerable to unauthorized actions, which could be combined with other vulnerabilities such as stored-XSS to further compromise user sessions.

A stored cross-site scripting (XSS) vulnerability exists in comfyanonymous/comfyui version 0.2.2 and possibly earlier. The vulnerability occurs when an attacker uploads an HTML file containing a malicious XSS payload via the /api/upload/image endpoint. The payload is executed when the file is viewed through the /view API endpoint, leading to potential execution of arbitrary JavaScript code.
