Summary

Mem0, persistent memory infrastructure for AI agents, prior to Python SDK 2.0.18 and TypeScript SDK 3.1.6 joins caller-controlled user_id, agent_id and run_id values using unescaped & and = delimiters, allowing another scope component to be embedded in an identifier so distinct tenant tuples produce the same session_scope key. Memory.add(), AsyncMemory.add() and REST POST /memories use that key to read and save raw messages, enabling cross-tenant conversation disclosure and eviction or interleaving of another tenant's history.

Risk Assessment

Conversation data may be disclosed and memory history integrity violated across tenants, posing a serious confidentiality risk in multi-tenant environments.

Recommendation

Update Mem0 Python SDK to version 2.0.18 or later and TypeScript SDK to version 3.1.6 or later.

Original NVD description (English source)

Mem0 provides persistent memory infrastructure for AI agents and applications. Prior to Python SDK 2.0.18 and TypeScript SDK 3.1.6, _build_session_scope() in mem0/memory/main.py and Memory.buildSessionScope() in the TypeScript SDK join caller-controlled user_id, agent_id, and run_id values using unescaped & and = delimiters. A caller can embed another scope component in a controlled identifier so that distinct tenant tuples produce the same session_scope key. Memory.add(), AsyncMemory.add(), and the REST POST /memories flow use that key to read and save recent raw messages, allowing cross-tenant conversation disclosure and eviction or interleaving of another tenant's history. This issue is fixed in Python SDK 2.0.18 and TypeScript SDK 3.1.6.
