CVE-2026-32767

SiYuan is a personal knowledge management system. Versions 3.6.0 and below contain an authorization bypass vulnerability in the /api/search/fullTextSearchBlock endpoint. When the method parameter is set to 2, the endpoint passes user-supplied input directly as a raw SQL statement to the underlying SQLite database without any authorization or read-only checks. This allows any authenticated user — including those with the Reader role — to execute arbitrary SQL statements (SELECT, DELETE, UPDATE, DROP TABLE, etc.) against the application's database. This is inconsistent with the application's own security model: the dedicated SQL endpoint (/api/query/sql) correctly requires both CheckAdminRole and CheckReadonly middleware, but the search endpoint bypasses these controls entirely. This issue has been fixed in version 3.6.1.

Summary
  • (es) SiYuan es un sistema de gestión de conocimiento personal. Las versiones 3.6.0 e inferiores contienen una vulnerabilidad de omisión de autorización en el endpoint /api/search/fullTextSearchBlock. Cuando el parámetro method se establece en 2, el endpoint pasa la entrada proporcionada por el usuario directamente como una sentencia SQL sin procesar a la base de datos SQLite subyacente sin ninguna autorización ni comprobación de solo lectura. Esto permite a cualquier usuario autenticado — incluidos aquellos con el rol de Lector — ejecutar sentencias SQL arbitrarias (SELECT, DELETE, UPDATE, DROP TABLE, etc.) contra la base de datos de la aplicación. Esto es inconsistente con el propio modelo de seguridad de la aplicación: el endpoint SQL dedicado (/api/query/sql) requiere correctamente el middleware CheckAdminRole y CheckReadonly, pero el endpoint de búsqueda omite estos controles por completo. Este problema ha sido solucionado en la versión 3.6.1.
