      "value": "SiYuan is an open-source personal knowledge management system. Prior to 3.7.1, the block search endpoint POST /api/search/fullTextSearchBlock concatenates attacker-controlled paths values into SQL predicates used by non-SQL search modes, allowing an unauthenticated publish visitor to inject a UNION SELECT and return rows from hidden documents by projecting an allowed visible box and path. This issue is fixed in versions 3.7.1."

Antes de la versión 3.7.1, el endpoint de búsqueda de bloques POST /api/search/fullTextSearchBlock concatena valores de rutas controlados por el atacante en predicados SQL utilizados por modos de búsqueda no SQL, permitiendo a un visitante de publicación no autenticado inyectar un UNION SELECT y devolver filas de documentos ocultos proyectando una caja y ruta visibles permitidas. Este problema está solucionado en las versiones 3.7.1."
