SCA: security update for github.com/siyuan-note/siyuan/kernel (GHSA-2h2p-mvfx-868w)

critical Tenable Self-Hosted Container Security Plugin ID 438512

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 3.5.10, a path traversal vulnerability in the
 /export endpoint allows an attacker to read arbitrary files from the server filesystem. By exploiting
 double‑encoded traversal sequences, an attacker can access sensitive files such as conf/conf.json, which
 contains secrets including the API token, cookie signing key, and workspace access authentication code.
 Leaking these secrets may enable administrative access to the SiYuan kernel API, and in certain deployment
 scenarios could potentially be chained into remote code execution (RCE). This vulnerability is fixed in
 3.5.10. (CVE-2026-30869)

Solution

Update the github.com/siyuan-note/siyuan/kernel library and its related packages to version 3.5.10 or later.
