CVE-2026-15746 Amazon CVE debrief

Who should care

Operators of Strands Agents using the elasticsearch_memory tool should assess exposure and prioritize upgrading to strands-agents-tools version 0.7.0 or later. They should also rotate their ELASTICSEARCH_API_KEY as a precautionary measure and review compensating controls for exposed systems. Additionally, they should verify exposure, review official advisories, and plan vendor-supported updates or mitigations through normal change control where exposure is

Why it matters

CVE-2026-15746 is a server-side request forgery (SSRF) issue in the elasticsearch_memory tool of strands-agents-tools package, potentially leading to disclosure of Elasticsearch API key and unauthorized access.

• Potential disclosure of Elasticsearch API key
• Possible unauthorized access to Elasticsearch cluster
• Need to verify exposure and upgrade to fixed version
• Requires rotation of ELASTICSEARCH_API_KEY as a precaution

Technical summary

The elasticsearch_memory tool in strands-agents-tools exposed connection parameters, allowing an LLM to control them. A crafted prompt could cause the tool to connect to a threat-actor-controlled server and disclose the operator's Elasticsearch API key. The issue was published on 2026-07-15T19:16:57.773Z and last modified on 2026-10-24T21:10:00.130Z. The tool's schema exposed parameters like es_url, cloud_id, and api_key, which could be controlled by the LLM. This could lead to unauthorized access to Elasticsearch clusters and potential disclosure of sensitive information.

Defensive priority

Operators of Strands Agents should assess exposure and prioritize upgrading to strands-agents-tools version 0.7.0 or later.

Recommended defensive actions

• Upgrade to strands-agents-tools version 0.7.0 or later
• Rotate ELASTICSEARCH_API_KEY as a precautionary measure
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed

Evidence notes

The CVE record and source references provide details on the SSRF issue in the elasticsearch_memory tool. The issue allows a large language model (LLM) to control connection parameters, potentially leading to disclosure of the Elasticsearch API key. Evidence is based on CVE details and source references, which may have limited information. Defenders should verify exposure and review official advisories for affected scope and severity.
