SiYuan versions up to and including v3.7.2 (fixed in v3.7.4) contain an information disclosure vulnerability in the /api/asset/getFileAnnotation endpoint, which returns .sya PDF-annotation file content without a publish-access check. Because the endpoint is gated only by CheckAuth (unlike the /assets/* route, which enforces publish access and password), an anonymous reader (when publish authentication is disabled) or any publish RoleReader who knows an asset path can read the private PDF annotations (highlights and notes) of publish-forbidden, password-protected, or unpublished documents. The issue is limited to non-encrypted notebooks; encrypted-box annotations are not exposed.

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

**CVE:** This vulnerability corresponds to [CVE-2026-72808](https://nvd.nist.gov/vuln/detail/CVE-2026-72808).

### Summary

The `/api/asset/getFileAnnotation` endpoint returns the content of `.sya` PDF-annotation files with no publish-access check. It is gated by `CheckAuth` only, so it is reachable by the publish `RoleReader` token and by the anonymous account when `Publish.Auth.Enable` is `false`. Its sibling, the `/assets/*` asset route does enforce publish access, including the publish password. An anonymous reader who knows an asset path can therefore read the private PDF annotations (highlights, notes) attached to assets in publish-forbidden, password-protected, or unpublished documents.

### Details

`getFileAnnotation` resolves the annotation file via `GetAssetAbsPathInBox` (no path traversal) and returns the `.sya` content. Unlike the `/assets/*` route, which applies the publish-access filter including password enforcement before serving asset bytes, `getFileAnnotation` applies no publish-access, publish-ignore, or password check. The guarded-sibling asymmetry indicates the boundary is meant to apply to this data and was omitted here.

`.sya` files for encrypted-box assets are fail-closed and not exposed. The gap is limited to non-encrypted assets.

**Route / auth tier.** `getFileAnnotation` is registered `CheckAuth`-only. `CheckAuth` admits `RoleReader`; the publish proxy forwards port-6808 traffic with a Reader JWT (anonymous when publish auth is disabled).
