Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior

backend/open_webui/utils/oauth.py (line ~1338). The function fetches arbitrary URLs from OAuth picture

internal resources and exfiltrate the full response. This vulnerability is fixed in 0.9.0.
