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.

**CVE:** This vulnerability corresponds to [CVE-2026-72798](https://nvd.nist.gov/vuln/detail/CVE-2026-72798).
### Summary
`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 access
