SCA: security update for github.com/siyuan-note/siyuan/kernel (GHSA-3g9h-9hp4-654v)

high Tenable Self-Hosted Container Security Plugin ID 438991

Description

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

- SiYuan is a personal knowledge management system. Prior to version 3.6.2, the SiYuan kernel WebSocket
server accepts unauthenticated connections when a specific "auth keepalive" query parameter is present.
After connection, incoming messages are parsed using unchecked type assertions on attacker-controlled
JSON. A remote attacker can send malformed messages that trigger a runtime panic, potentially crashing the
kernel process and causing denial of service. Version 3.6.2 fixes the issue. (CVE-2026-33203)

Solution

Update the github.com/siyuan-note/siyuan/kernel library and its related packages to version 3.6.2 or later.
