Threat Intelligence Brief
Curated summary with source attribution

Threat Risk: High
Victim: Amazon Kiro IDE users
Incident: Prompt injection vulnerability in Amazon Kiro IDE.
Impact: Unauthorized exfiltration of local sensitive data to attacker-controlled servers.
Attacker: Unidentified threat actors
Analysis: The vulnerability exploits the agentic nature of the Kiro IDE, where the AI interprets repository contents as actionable instructions rather than passive code. By manipulating workspace configurations and steering files, attackers can force the AI to exfiltrate sensitive data via native networking features without requiring traditional RCE or malicious user prompts. This demonstrates a new attack vector where the AI agent becomes the primary execution engine for the exploit.
Recommendations: Update Amazon Kiro IDE to version 0.8.140 or newer immediately.; Avoid opening workspace files from untrusted or third-party sources.; Restrict network egress for development tools to prevent unauthorized data exfiltration.
