OWASP Just Ranked Agent Identity Abuse as the #3 Risk in Agentic AI. Here Is Why.

The OWASP Top 10 for Agentic Applications 2026 is out — a peer-reviewed framework from 100+ security experts identifying the most critical risks facing autonomous AI systems. Identity & Privilege Abuse landed at #3 . Not prompt injection (#1). Not tool misuse (#2). Identity is the third most dangerous attack surface in agentic AI. What ASI03 Says Agents operate with credentials or delegated authority, inheriting identity context from humans or other services. The attack: exploit dynamic trust to perform actions the original owner never intended. OWASP's examples: A privileged agent shares full credentials with a lower-privilege agent Cached credentials are reused across sessions, granting access to restricted systems A fake internal "helper" agent is trusted to perform administrative actions Their mitigations: Give each agent a unique, bounded identity with short-lived credentials Isolate agent sessions and wipe cached context between tasks Require re-authorization for privilege escala
