Affected Systems
AWS Kiro agentic coding IDE, all versions prior to patch. Vulnerability allowed attackers to manipulate configuration files via hidden web page content without user consent.
Exploitation Status
Vulnerability discovered by Intezer and Kodem Security researchers. No CVE assigned. AWS has released a patch. No evidence of active exploitation in the wild reported.
Business Impact
Development teams using AWS Kiro were at risk of remote code execution through social engineering attacks. Attackers could embed malicious instructions in web pages (invisible to users) that would be processed by the IDE, rewriting configuration files and executing arbitrary code. This could lead to supply chain compromise, credential theft, or lateral movement within development environments. Patch is available, reducing immediate risk.
Urgency
🟠Within 24 hours
Recommended Actions
- Immediately update AWS Kiro IDE to the latest patched version across all developer workstations
- Review AWS Kiro configuration files for unauthorized modifications made prior to patching
- Audit developer workstation logs for suspicious file writes or configuration changes in Kiro directories
- Implement network segmentation to isolate developer environments from untrusted web content
- Educate development teams on risks of AI-assisted IDEs processing untrusted web content and enforce browsing hygiene
