The flaw, which currently has no CVE identifier assigned, affects Kiro IDE version 0.7.45 on Windows. It was disclosed without a patch being immediately available.

• Affected product: Amazon Kiro IDE 0.7.45
• Platform: Windows
• Attack vector: Prompt injection via malicious content processed by Kiro Powers
• Impact: Potential exfiltration of sensitive project data or credentials

The attack works by crafting a malicious prompt or injecting instructions into content that the IDE processes. When Kiro Powers acts on the injected instructions, it can be manipulated into sending data to an attacker-controlled endpoint. This is particularly concerning because agentic IDEs have access to source code, environment variables, and other development secrets.

Given that Kiro is designed to operate with high-level autonomy, the research highlights a broader risk: the more permissions an AI assistant has, the more damage a successful prompt injection can cause. Organizations using agentic coding tools should review how they sandbox AI-driven actions and monitor for unusual outbound network requests.
