CVE-2026-31243

The mem0 1.0.0 server lacks authentication and authorization controls for its memory reset and table re-creation functionality accessible via the DELETE /memories endpoint. An unauthenticated attacker can send a DELETE request that triggers a reset operation, leading to the execution of a CREATE TABLE SQL statement. This can cause unexpected table re-creation, schema disruption, potential data loss, and denial of service for the memory management service.

Summary		(es) El servidor mem0 1.0.0 carece de controles de autenticación y autorización para su funcionalidad de restablecimiento de memoria y recreación de tablas accesible a través del endpoint DELETE /memories. Un atacante no autenticado puede enviar una solicitud DELETE que desencadena una operación de restablecimiento, lo que lleva a la ejecución de una sentencia SQL CREATE TABLE. Esto puede causar una recreación inesperada de tablas, interrupción del esquema, posible pérdida de datos y denegación de servicio para el servicio de gestión de memoria.
