CyberRota Analysis

AI-Generated

ComfyUI versions prior to 0.28.0 are vulnerable to stored cross-site scripting (XSS) due to inadequate handling of SVG files at the /view endpoint, which allows attackers to inject malicious scripts. This vulnerability can lead to unauthorized actions being performed on behalf of users or the exposure of sensitive information. Organizations using ComfyUI should prioritize upgrading to version 0.28.0 to mitigate the risk of exploitation.

Original NVD Description

ComfyUI is a modular diffusion model GUI, api and backend with a graph/nodes interface. Prior to 0.28.0, the /view endpoint served uploaded SVG files inline because image/svg+xml and related XML content types were absent from the dangerous-content-type handling, allowing stored cross-site scripting in the ComfyUI origin. This issue is fixed in version 0.28.0.
