What is CVE-2026-31243?

The mem0 server version 1.0.0 is vulnerable due to inadequate authentication and authorization controls that affect its memory reset and table re-creation functionalities. An attacker without authentication can send a DELETE request to the /memories endpoint, inadvertently triggering a reset operation that executes a CREATE TABLE SQL statement. This action can result in unintended table re-creation, disrupt the database schema, compromise data integrity, and even lead to denial of service within the memory management service.
