Description
SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the getRefIDsByFileAnnotationID endpoint that returns block identifiers citing PDF annotations without publish-access filtering. Attackers can extract block identifiers from restricted documents by supplying annotation identifiers visible in published pages, revealing citation relationships across forbidden and password-protected tiers.
