Strands Agents Tools vulnerabilities

Improper neutralization of input used for LLM prompting in the environment tool in Strands Agents Tools before 0.8.6 might allow remote actors to obtain the agent host's environment variables in cleartext, including cloud credentials and API keys, via a crafted prompt that disables the tool's secret masking. To remediate this issue, users should upgrade to version 0.8.6 or later and rotate any credentials that were present in the environment of agents that loaded the environment tool.

In Strands Agents Tools before 0.8.2, incorrect authorization in the http_request tool may allow remote attackers to obtain credentials configured via HTTP_REQUEST_TOKEN_CONFIG by influencing the LLM to route requests through attacker-controlled proxy infrastructure.

A server-side request forgery (SSRF) vulnerability was found in the elasticsearch_memory tool of the strands-agents-tools package. Connection parameters (es_url, cloud_id, api_key) were controllable by the LLM, and omitting api_key caused the operator's API key to be sent to any host specified by the LLM.
