CVE-2026-72798: SiYuan: Publish-access filter on renderAttributeView leaves related-database content unfiltered and fails open on non-block first columns
renderAttributeView correctly applies the reader publish-access filter, but the filter’s row-accessibility decision is keyed solely to the row’s first cell, and it never inspects the remaining cells’ values. Relation and Rollup cells carry mirrored content from a different database, so a row belonging to a published database can hand an anonymous reader the contents of a related database whose host document is hidden, publish-forbidden, or password-protected. Separately, when the first column is not a block value the accessibility check is skipped entirely and the row is returned unchecked.
