CVE-2025-49126

8.8 HIGH 0.3% exploit odds Fix listed XSS Web app

What it is

Visionatrix is an AI Media processing tool using ComfyUI. In versions 1.5.0 to before 2.5.1, the /docs/flows endpoint is vulnerable to a Reflected XSS (Cross-Site Scripting) attack allowing full takeover of the application and exfiltration of secrets stored in the application. The implementation uses the get_swagger_ui_html function from FastAPI. This function does not encode or sanitize its arguments before using them to generate the HTML for the swagger documentation page and is not intended to be used with user-controlled arguments. Any user of this application can be targeted with a one-click attack that can takeover their session and all the secrets that may be contained within it. This issue has been patched in version 2.5.1.
