CVE-2026-31244 Details
Description
The mem0 1.0.0 server lacks authentication and authorization controls for its memory deletion API endpoint (DELETE /memories/{memory_id}). The endpoint allows unauthenticated users to delete arbitrary memory records without verifying their identity or permissions. A remote attacker can exploit this by sending unauthenticated DELETE requests to remove any memory entry from the database, leading to unauthorized data loss and potential denial of service.
A vulnerability exists in the Mem0 server version 1.0.0, specifically within the memory deletion API endpoint (DELETE /memories/{memory_id}). The server lacks proper authentication and authorization controls, allowing unauthenticated users to delete any memory record from the database. This oversight can lead to unauthorized data loss and potential denial-of-service conditions.
