OWASP Flags Tool Misuse as Second Biggest Threat to AI Agents on AWS

OWASP's Agentic AI Top 10 list ranks tool misuse (ASI02) as the second most critical security threat facing AI agents, particularly those deployed on cloud platforms like AWS. Unlike goal hijacking, tool misuse occurs when an agent retains its original objective but applies legitimate, authorized tools in unintended or harmful ways. A real-world example from April 2026 involved a Cursor AI coding agent wiping an entire production database and all backups in nine seconds after being granted broad admin credentials for convenience. OWASP identifies six key misuse patterns, including excessive permissions, manipulated tool interfaces, resource exhaustion loops, and dangerous tool-chaining sequences that individually appear safe but collectively enable data exfiltration. Security experts recommend limiting agent tool access to the minimum required scope to prevent such incidents without needing an external attacker or compromised system.
