SiYuan versions before v3.7.4 fail to apply publish-access filtering to the getAttributeViewKeysByID endpoint, allowing authenticated readers to retrieve complete database column schemas including descriptions, select vocabularies, and template expressions. Additionally, getBlockDefIDsByRefText and getBlockRelevantIDs endpoints enumerate workspace-wide block IDs without publish scoping, enabling attackers to discover valid block identifiers across publish boundaries and access content from hidden or password-protected documents.
