SiYuan versions before v3.7.4 fail to properly filter related-database content in renderAttributeView, allowing anonymous readers to access Relation and Rollup cell contents from hidden or password-protected databases. Attackers can request published databases that relate to restricted databases to retrieve sensitive content, or bypass row filtering entirely when the first column is a non-block type.
