Description
SiYuan versions before v3.7.4 fail to validate publish-password tier in getGraph and getLocalGraph endpoints, allowing anonymous readers to retrieve block-level content of password-protected documents. Attackers can call these endpoints without supplying a password to read protected document content and the complete reference topology.
