CVSS 3.1
7.7 highCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:NCVE-2026-45338
High (7.7) in openwebui open webui. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in open-webui 0.9.0.
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, a Server-Side Request Forgery (SSRF) vulnerability exists in _process_picture_url() in backend/open_webui/utils/oauth.py (line ~1338). The function fetches arbitrary URLs from OAuth picture claims without applying validate_url(), allowing an attacker to force the server to make HTTP requests to internal resources and exfiltrate the full response. This vulnerability is fixed in 0.9.0.
