Official description

** 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 Reason: This candidate was withdrawn by its CNA.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)."
