SiYuan's development branch (endpoint introduced by commit 9b8e8956f, not present in v3.7.3 or master, patched in v3.7.4-alpha.3) 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.

Summary
  • (es) La rama de desarrollo de SiYuan (endpoint introducido por el commit 9b8e8956f, no presente en v3.7.3 o master, parcheado en v3.7.4) contiene una vulnerabilidad de autorización faltante en el endpoint /api/av/getAttributeViewSearchTarget. La ruta está registrada solo con CheckAuth y no realiza comprobaciones de autorización (sin CheckReadonly, sin acceso de publicación o control de cuaderno cifrado). Dado un identificador de base de datos tomado de una página publicada y una palabra clave, un lector anónimo puede consultar el endpoint para recuperar contenido de fila de base de datos coincidente, incluyendo filas que los filtros de publicación (FilterAttributeViewByPublishAccess) retendrían de otro modo. Ninguna versión estable publicada está afectada.
