CVE-2025-2835Public exploitNetwork attack vector

Authenticated SSRF via unrestricted autoLink destination

Published Mar 27, 2025 · Updated Mar 27, 2025

Server-side request forgery in zhangyd-c OneBlog 2.3.9 and earlier allows remote authenticated users to send server-side requests. RestApiController.autoLink accepts a Link object and uses its destination for the self-service link request without restricting the server-side destination. A low-privilege account can cause OneBlog to contact attacker-chosen network destinations, with impact limited to the resulting requests.
