AWS Kiro, an agentic coding IDE, was vulnerable to remote code execution when processing untrusted web content containing hidden text. An attacker could craft a poisoned webpage that, when summarized or processed by Kiro, would trigger configuration rewriting and arbitrary code execution on the developer's machine without approval.
What to do
Ensure all agentic tools implement strict input validation and sandboxing before processing untrusted external content.
