Affected Systems

AWS Kiro agentic coding IDE (specific versions not disclosed). Vulnerability has been patched by AWS. Users who installed Kiro before the patch are potentially affected.

Exploitation Status

Vulnerability discovered by Intezer and Kodem Security researchers. No CVE assigned. No public reports of active exploitation. Proof-of-concept demonstrated by researchers. AWS has released a patch.

Business Impact

Development teams using AWS Kiro faced remote code execution risk through social engineering attacks. Attackers could embed hidden text in web pages that, when viewed by Kiro users, would silently rewrite configuration files and execute arbitrary code without user consent. This bypassed normal approval workflows. Impact limited to organizations that adopted Kiro IDE. Patch availability reduces ongoing risk, but unpatched instances remain vulnerable.

Recommended Actions

  • Identify all instances of AWS Kiro IDE deployed in the development environment and verify patch status
  • Update AWS Kiro to the latest patched version immediately on all developer workstations
  • Review Kiro configuration files for unauthorized modifications made before patching
  • Educate developers about risks of browsing untrusted web content while using agentic AI coding tools
  • Monitor developer workstation logs for unusual process execution or configuration changes associated with Kiro
