high Tenable Cloud Security Plugin ID 472183

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-74802)

Solution

Update the github.com/siyuan-note/siyuan/kernel library and its related packages to version 0.0.0-20260803045322-cb67e0b4fab5 or later.
