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.

SiYuan: Missing publish-access filter on getAttributeViewKeysByID discloses database column schema, plus two unscoped block-ID enumeration oracles (publish mode)
**CVE:** This vulnerability corresponds to [CVE-2026-72800](https://nvd.nist.gov/vuln/detail/CVE-2026-72800).
### Summary
`POST /api/av/getAttributeViewKeysByID` returns a database's full column schema with no publish-access filtering, while its sibling `getAttributeViewKeys` applies the filter for reader sessions. Two further endpoints, `getBlockDefIDsByRefText` and `getBlockRelevantIDs` return workspace-wide block IDs with no publish scoping. All three are `CheckAuth`-only, so they are reachable by the publish `RoleReader` token and by the anonymous account when `Publish.Auth.Enable` is `false`.
