SiYuan: Publish-boundary bypass via WebSocket broadcast: anonymous readers receive a live unfiltered feed of all edits including protected/forbidden documents (publish mode)
Impact
SiYuan versions before v3.7.4 contain a publish-boundary bypass vulnerability in WebSocket broadcast sessions that allows anonymous readers to receive unfiltered edits. Attackers can establish a WebSocket connection to the publish surface and passively receive real-time content events including password-protected and forbidden documents without authentication.
