🛡 OWASP Agentic Top 10 Has Reached Production The OWASP Top 10 for Agentic Applications 2026, peer-reviewed by 100+ industry experts, has cemented itself as the security baseline for agent builds. Of its 10 risks (ASI01-ASI10), three of the top four (ASI02-ASI04) revolve around identity, tools, and delegated trust boundaries — and without precise mitigation at the code level, a production agent ends up exposed to arbitrary requests in Phase 1. This post walks through the production-ready mitigation patterns for the five most critical risks in Next.js App Router, with a summary table for the remaining five. The non-technical 5-minute checklist version lives in the companion piece AI Agent Security OWASP Top 10 — 5-Minute Self-Check for Non-Developers . Here we approach the same framework from a developer's lens, in actual code patterns. For integrating ML-based safety layers like Lakera Guard, see Lakera Guard in 30 Lines , which sketches out the rest of the security stack.…
