Rejected reason: ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by its CNA. Further investigation showed that it was not a security issue. Notes: The vendor explains: "The 't0p-s3cr3t' default was dead code on every supported startup path: start.sh, start_windows.bat and `open-webui serve` all set or auto-generate WEBUI_SECRET_KEY before the backend imports env.py. It was only ever reachable by invoking uvicorn directly, which is unsupported and unsafe (the app would then sign tokens/cookies with a public, hardcoded key)."

A security vulnerability has been detected in open-webui up to 0.6.16. Affected is an unknown function of the file backend/start_windows.bat of the component JWT Key Handler. Such manipulation of the argument WEBUI_SECRET_KEY leads to insufficiently random values. It is possible to launch the attack remotely. The attack requires a high level of complexity. The exploitability is told to be difficult. The exploit has been disclosed publicly and may be used.
