MEDIUM

mem0 1.0.0 - Unauthenticated Arbitrary Memory Record Creation via Memory Creation API Endpoint

Title source: llm
STIX 2.1

Description

The mem0 1.0.0 server lacks authentication and authorization controls for its memory creation API endpoint (POST /memories). The endpoint allows unauthenticated users to submit arbitrary memory records without verifying their identity or permissions. A remote attacker can exploit this by sending unauthenticated POST requests to create malicious or spoofed memory entries in the database, leading to unauthorized data injection and potential data pollution.
