CVE-2026-32750Public exploitNetwork attack vector

Host file disclosure via unrestricted directory import

Published Mar 19, 2026 · Updated Mar 19, 2026

Path traversal in SiYuan before 3.6.1 allows remote authenticated users to expose readable host files through a crafted import request. POST /api/import/importStdMd sends the supplied localPath to model.ImportFromLocalPath without workspace-boundary or sensitive-path checks, recursively storing readable files as persistent notes. Administrator access is required to invoke the import; the resulting content survives restarts and is searchable by workspace users, including Publish Service Reader accounts.
