Summary

SiYuan versions before v3.7.4 contain an arbitrary file deletion vulnerability in the /api/search/removeTemplate endpoint that accepts an unvalidated path parameter passed directly to os.RemoveAll. Authenticated admin attackers can supply absolute filesystem paths to recursively delete any file or directory the kernel process has permission to remove, anywhere on the host filesystem.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of siyuan-note/siyuan published their own advisory on GitHub. Reviewed sources take precedence over it.
