What is CVE-2026-32110?

The SiYuan Personal Knowledge Management System is susceptible to an arbitrary HTTP request vulnerability within the /api/network/forwardProxy endpoint. Prior to version 3.6.0, this endpoint permits authenticated users to submit user-controlled URLs, which can then trigger HTTP requests from the server. This lack of stringent URL validation allows attackers to redirect requests to sensitive internal networks, localhost, or even cloud metadata services, exposing systems to potential data leaks and unauthorized access. The issue has been addressed in version 3.6.0, which implements necessary security measures to prevent exploitation.
