SCA: security update for github.com/siyuan-note/siyuan/kernel (GHSA-94c7-g2fj-7682)

high Tenable Self-Hosted Container Security Plugin ID 436847

Description

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

- SiYuan is a personal knowledge management system. Versions prior to 3.5.4 contain a logic vulnerability in
the /api/file/globalCopyFiles endpoint. The function allows authenticated users to copy files from any
location on the server's filesystem into the application's workspace without proper path validation. The
vulnerability exists in the api/file.go source code. The function globalCopyFiles accepts a list of source
paths (srcs) from the JSON request body. While the code checks if the source file exists using
filelock.IsExist(src), it fails to validate whether the source path resides within the authorized
workspace directory. Version 3.5.4 patches the issue. (CVE-2026-23851)
