SiYuan versions before v3.7.3 contain a metadata disclosure vulnerability in the /api/block/getBlockInfo endpoint that returns document root metadata including title for publish-forbidden documents without publish-access checks. Anonymous readers or publish RoleReader tokens can supply a block ID to retrieve the title, notebook, path, root ID, and icon of documents administrators marked as excluded from publishing.

Affected: Go: github.com/siyuan-note/siyuan/kernel

**CVE:** This vulnerability corresponds to [CVE-2026-68585](https://nvd.nist.gov/vuln/detail/CVE-2026-68585).

### Summary

The `/api/block/getBlockInfo` endpoint returns document root metadata including the document title (`rootTitle`) for a block in a publish-forbidden document, with no publish-access check. Its sibling `/api/block/getDocInfo` applies the publish-access filter, `getBlockInfo` does not. Both are gated by `CheckAuth` only, so `getBlockInfo` is reachable by the publish `RoleReader` token and by the anonymous account when `Publish.Auth.Enable` is `false`.

### Details

The list/info side of this API is filtered while the block-info twin is not the asymmetry indicates an oversight rather than intended behavior:

| Endpoint | Returns | Publish-access filter | Route | |---|---|---|---| | `getDocInfo` | document info/metadata | present | `CheckAuth` | | `getBlockInfo` | `box, path, rootID, rootTitle, rootChildID, rootIcon` | none | `CheckAuth` |

`getBlockInfo` takes a caller-supplied block ID, validates only its format, and returns the containing document's root metadata including `rootTitle` (the document title) with no `IsReadOnlyRoleContext` / publish-access check. Because `getDocInfo` performs the filtering for equivalent data, the boundary is clearly meant to apply here; `getBlockInfo` omits it.

### Proof of Concept

Reproduced on a local instance (SiYuan running locally, publish mode enabled on port 6808, publish Basic Auth disabled). Setup: a publish-forb…
