Amazon Kiro Prompt Injection Can Exfiltrate Sensitive Data Through Kiro Powers
Cybersecurity researchers have disclosed details of a vulnerability in Amazon Kiro, an artificial intelligence (AI)-powered, agentic integrated development environment (IDE), that could facilitate data exfiltration via prompt injection and Kiro Powers. The security flaw, which does not have a CVE identifier, works against Kiro IDE 0.7.45 on Windows, according to Mindguard. The latest version of the IDE is 1.0.337. "The issue allowed attacker-controlled repository content to influence the Kiro agent and ultimately cause sensitive local information to be transmitted to an external endpoint," security researcher Fergal Glynn said in a report shared with The Hacker News. Kiro Powers goes beyond skills by bundling Model Context Protocol (MCP) server configurations, steering files ("POWER.md"), hooks, and contextual knowledge. The steering file is like an "onboarding manual" that provides persistent context and tells the AI agent what MCP tools are ava...
