Summary
The openmemory/api component in mem0 contains an unauthenticated access vulnerability that allows unauthenticated attackers to read, write, and delete arbitrary user memories by accessing API routers registered without authentication middleware. Attackers can supply arbitrary user_id parameters or directly access memory retrieval endpoints to expose private memory content, or invoke pause endpoints with global_pause=true to cause denial-of-service across all users.
Risk Assessment
The risk includes unauthorized access to sensitive user data and the possibility of a complete denial-of-service attack, leading to privacy breaches and system unavailability.
Recommendation
Immediately add authentication middleware to all API routers in the openmemory/api component and verify that no endpoint is accessible without authorization. Also implement restrictions for parameters such as global_pause.
