CVE-2026-34225Public exploitNetwork attack vector

Internal network probing via unrestricted image fetch

Published Apr 14, 2026 · Updated Apr 14, 2026

Blind SSRF in Open WebUI 0.6.35 through 0.9.4 allows remote authenticated users to probe internal services through image editing. The image_edits handler passes each user-supplied HTTP or HTTPS image URL to requests.get without restricting its destination. Any verified account can distinguish successful and failed fetches to scan internal ports, but the response body is not returned.
