CVE-2024-21575 Information

Description

ComfyUI-Impact-Pack is vulnerable to Path Traversal. The issue stems from missing validation of the image.filename field in a POST request sent to the /upload/temp endpoint added by the extension to the server. This results in writing arbitrary files to the file system which may under some conditions result in remote code execution (RCE).
