Duplicate Advisory: SiYuan: getAttributeViewSearchTarget returns database row content to anonymous readers with no publish-access check, reopening the class closed one day earlier at the adjacent route

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-9cqf-hhrq-7v45. This link is maintained to preserve external references.

Original Description

SiYuan's development branch (endpoint introduced by commit 9b8e8956f, not present in v3.7.3 or master, patched in v3.7.4) contains a missing-authorization vulnerability in the /api/av/getAttributeViewSearchTarget endpoint. The route is registered with CheckAuth only and performs no authorization checks (no CheckReadonly, no publish-access or encrypted-notebook gating). Given a database identifier taken from a published page and a keyword, an anonymous reader can query the endpoint to retrieve matching database row content, including rows that publish filters (FilterAttributeViewByPublishAccess) would otherwise withhold. No released stable version is affected.

Severity

8.6 (High)
