CVE-2026-31242

The mem0 v1.0.0 server lacks authentication and authorization controls for its memory reset 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 DROP TABLE SQL statement. This results in the deletion of the entire memory database table, causing catastrophic data loss and a complete denial of service for all users of the service.

Summary		(es) El servidor mem0 v1.0.0 carece de controles de autenticación y autorización para su funcionalidad de restablecimiento de memoria 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 DROP TABLE. Esto resulta en la eliminación de toda la tabla de la base de datos de memoria, causando una pérdida de datos catastrófica y una denegación de servicio completa para todos los usuarios del servicio.
