CVE-2026-31243 Details
Description
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.
A vulnerability in the Mem0 server version 1.0.0 allows for unauthorized memory reset and table re-creation actions. The issue arises from the absence of authentication and authorization controls on the DELETE /memories endpoint. This flaw enables an unauthenticated attacker to send a DELETE request that initiates a memory reset, which in turn executes a CREATE TABLE SQL command. The consequences include unexpected table re-creation, disruption of the database schema, potential data loss, and a denial-of-service condition for the memory management service.
