NewCVE-2026-116575 (opens in a new tab)How to fix?
Upgrade mem0ai to version 2.0.18 or higher.
Overview
mem0ai is a Long-term memory for AI Agents
Affected versions of this package are vulnerable to Incorrect Authorization via the buildSessionScope function (TypeScript) and _build_session_scope function (Python), which construct a session scope key by concatenating entity ID values using = and & as structural delimiters without escaping those characters in the values themselves. An attacker who controls the user_id, agent_id, or run_id filter values can inject delimiter characters to manipulate the resulting scope key, causing one session's scope to collide with or be confused for another's, leading to unauthorized read or write access to memory belonging to a different session identity.
