Duplicate Advisory: SiYuan: Cross-Site WebSocket Hijacking on the admin-only network proxy endpoint (`/ws/network/proxy`) via explicit `CheckOrigin: true` bypass

Published Aug 17, 2026·Updated Oct 2, 2026

NVD Description

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-3cc2-h3v6-rqpq. This link is maintained to preserve external references. ## Original Description SiYuan versions before 3.7.4 contain a cross-site WebSocket hijacking vulnerability in the admin-only /ws/network/proxy endpoint that explicitly disables origin validation by setting CheckOrigin to unconditionally return true. Attackers can craft malicious webpages that establish WebSocket connections to this endpoint and direct the SiYuan kernel process to proxy arbitrary network traffic to attacker-chosen targets, enabling authenticated network pivoting through the victim's machine.
