Go to dashboardSiYuan versions before 3.7.4 have an admin-only WebSocket endpoint, /ws/network/proxy, that disables origin checks, so any webpage the user opens can connect to it. An attacker's page can then make the SiYuan kernel proxy arbitrary network traffic to targets they choose, pivoting through the victim's machine.

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.
