Bulletin ID: 2026-077-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 08/06/2026 11:00 AM PDT Description: Strands Agents is an open-source SDK for building AI agents. The strands-agents-tools package provides pre-built tools for use with the SDK, including the mongodb_memory, elasticsearch_memory, and mem0_memory tools for storing and retrieving agent memories. We identified CVE-2026-19111, an insecure direct object reference (IDOR) issue in the mongodb_memory, elasticsearch_memory, and mem0_memory tools. Each tool uses a namespace field as the sole tenant-isolation key, and that namespace was exposed as a parameter the large language model (LLM) could control through the tool schema. A crafted prompt could cause a tool to emit a call with a forged namespace, allowing a remote authenticated user to read, modify, or delete memories belonging to other tenants, or to inject false memories into another tenant's namespace. The standalone mongodb_memory and elasticsearch_memory functions additionally exposed connection parameters, which could allow the memory layer to be redirected to an actor-specified cluster.

Bulletin ID: 2026-072-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 08/03/2026 13:30 PM PDT Description: Strands Agents is an open-source SDK for building AI agents. The strands-agents-tools package provides pre-built tools for use with the SDK, including the shell tool for executing operating system commands on the agent's host. We identified CVE-2026-18733. The shell tool includes a human consent gate that prompts the operator to approve commands before they run. The tool also exposed a non_interactive parameter in the input schema that the large language model (LLM) could control. A crafted prompt, for example one delivered through untrusted content the agent reads (indirect prompt injection), could set non_interactive to true, which bypasses the consent gate and allows arbitrary operating system commands to execute on the agent's host without operator approval.
