CVE-2026-72799

SiYuan before v3.7.4 (affected <=v3.7.2) fails to enforce publish-access filters on five filetree path-resolution endpoints (getFullHPathByID, getHPathByID, getPathByID, getIDsByHPath, and getHPathByPath). In publish mode, when Publish.Auth.Enable is false, an unauthenticated (anonymous) reader — or any publish reader token — can call these endpoints to enumerate the complete private document tree, mapping notebook names, folder hierarchies, and document titles, and resolving title paths to document IDs, including for documents marked hidden, password-protected, or publish-forbidden.
