SCA: security update for github.com/siyuan-note/siyuan/kernel (GHSA-vw86-c94w-v3x4)

high Tenable Cloud Security Plugin ID 440459

Description

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

 - SiYuan is an open-source personal knowledge management system. In versions 3.6.3 and prior, the
 /api/av/removeUnusedAttributeView endpoint constructs a filesystem path using the user-controlled id
 parameter without validation or path boundary enforcement. An attacker can inject path traversal sequences
 such as ../ into the id value to escape the intended directory and delete arbitrary .json files on the
 server, including global configuration files and workspace metadata. This issue has been fixed in version
 3.6.4. (CVE-2026-40318)

Solution

Update the github.com/siyuan-note/siyuan/kernel library and its related packages to version 3.6.40.0.0-20260407035653-2f416e5253f1 or later.
