A critical vulnerability in AWS Kiro allowed a malicious web page to rewrite its configuration file and execute arbitrary code without user approval. The flaw exploited the IDE's trust in its own configuration files, enabling remote code execution through hidden text injection.

Hidden text on a web page was enough to make Kiro, AWS's agentic coding IDE, rewrite its own configuration file and run an attacker's code on a developer's machine, with no approval step able to stop it.

Intezer, in research with Kodem Security, found that a request as ordinary as asking Kiro to summarize a page could end in remote code execution. AWS has patched the issue, and no CVE has been
