Executive brief
A vulnerability exists in the mem0 server, a tool used to provide memory layers for AI agents. An unauthenticated user can remotely trigger a command that resets the system's memory and recreates database tables. This can lead to total data loss, disruption of AI services, and a complete denial of service for the memory management platform.
Technical details
The mem0 1.0.0 server is vulnerable to missing authentication (CWE-306) and missing authorization (CWE-862) on its 'DELETE /memories' endpoint. An unauthenticated remote attacker can send a DELETE request to this endpoint, which triggers a memory reset operation. This operation executes a 'CREATE TABLE' SQL statement, causing existing tables to be dropped or recreated. This results in schema disruption, permanent data loss, and a denial of service (DoS) for the memory management service. The attack requires no special privileges or user interaction.
