Executive brief
AWS Strands Agents Tools includes a memory component used by AI agents to store and retrieve contextual information. An insecure direct object reference vulnerability in the memory tools allows an attacker to access or manipulate data belonging to other users or agents without proper authorization, potentially exposing sensitive conversation history, business logic, or credentials used by the AI system.
Technical details
The vulnerability is classified as an insecure direct object reference (IDOR) in the memory tools subsystem of AWS Strands Agents Tools. The root cause involves insufficient authorization validation when accessing memory objects, allowing attackers to directly reference objects belonging to other users or agents by manipulating identifiers. The attack likely requires network access to the Agents Tools API and may require prior authentication or knowledge of valid object identifiers. Successful exploitation allows an attacker to read, modify, or delete memory records associated with other agents or users, potentially exposing sensitive application state or business data. AWS has published this vulnerability and patching guidance should be available through standard AWS security channels.
