AWS Fixes Code Injection and SSRF in Bedrock AgentCore Starter Toolkit
Tech GuruQuick Answer
Amazon Web Services published 2026-127-AWS for bedrock-agentcore-starter-toolkit 0.1.4 through releases before 0.3.14. Inventory the exact affected scope, apply bedrock-agentcore-starter-toolkit 0.3.14; re-import agents and replace generated local or deployed artifacts; plan migration to @aws/agentcore, validate dependent operations, and preserve change evidence.
Validate Bedrock AgentCore Starter Toolkit Scope And Apply The Supported Fix
What to do now: Inventory bedrock-agentcore-starter-toolkit 0.1.4 through releases before 0.3.14, match versions and enabled features to the authority's scope, apply supported remediation, validate representative operations, and document exceptions.

What Changed
AWS corrected arbitrary code execution during malicious agent import and external-reference handling that could access unintended network resources or local files.
What To Validate Now
- Inventory. Locate bedrock-agentcore-starter-toolkit 0.1.4 through releases before 0.3.14; record versions, enabled features, exposure paths, owners, dependencies, support channels, and maintenance groups.
- Establish applicability. Compare every deployment with the authority's affected statement: bedrock-agentcore-starter-toolkit versions 0.1.4 and later but earlier than 0.3.14 when importing, running, or deploying untrusted agent content. Do not infer applicability from product family, CVSS, or Internet reachability alone.
- Remediate. Apply bedrock-agentcore-starter-toolkit 0.3.14; re-import agents and replace generated local or deployed artifacts; plan migration to @aws/agentcore through the authority-supported channel and follow the current advisory.
- Validate. Confirm the resulting Bedrock AgentCore Starter Toolkit build or managed state, exercise representative services and recovery paths, monitor for regressions, and retain the result.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
The Starter Toolkit is deprecated. Treat imported agent projects and generated deployment artifacts as untrusted until rebuilt from validated sources with the fixed package. Preserve pre-change state, installation output, logs, validation evidence, and rollback decisions.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
