CVE-2026-15746
Bulletin ID: 2026-056-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 07/15/2026 11:30 AM PDT Description: Strands Agents is an open-source Python SDK for building and running AI agents. The strands-agents-tools package provides pre-built tools for use with the SDK, including the elasticsearch_memory tool for agent memory storage. We identified CVE-2026-15746, a server-side request forgery (SSRF) issue in the elasticsearch_memory tool. The tool exposed its connection parameters (es_url, cloud_id, api_key) as fields the large language model (LLM) could control through the tool schema. When a caller omitted the api_key parameter, the tool fell back to the operator's ELASTICSEARCH_API_KEY environment variable and sent it to whichever host the LLM specified. A crafted prompt could cause the tool to connect to a threat-actor-controlled server and disclose the operator's Elasticsearch API key in the Authorization header. Impacted versions: < 0.7.0 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
