CVE-2026-72789
SiYuan: The publish-access gate treats encrypted notebooks as publicly accessible by default, allowing anonymous readers to retrieve fully decrypted document content while a notebook is unlocked
Impact
SiYuan before v3.7.4 fails to properly validate publish access for encrypted notebooks, treating them as publicly accessible by default. Anonymous readers can enumerate and retrieve fully decrypted document content from unlocked encrypted notebooks through the publish API without authentication or key material.
