CVE-2026-6625Public exploitNetwork attack vector

Server-side requests via unvalidated OAuth avatar URL

Published Apr 20, 2026 · Updated Apr 20, 2026

SSRF in Mogu Blog v2 5.0 through 5.2 allows remote attackers to make its picture service fetch attacker-selected URLs. LocalFileServiceImpl.uploadPictureByUrl constructs a java.net.URL from an OAuth avatar value and calls URLConnection.getInputStream without checking the scheme, destination host, or resolved address. Exploitation requires control of an OAuth provider response and a user to complete that OAuth login, after which the server can reach internal services or local files and save the response as an image.
