OWASP Agentic AI Top 10 becomes de facto security baseline

OWASP’s Agentic AI Top 10—initially released as a draft earlier in the year—has now solidified into the reference document for agent-security threats, and over the past few days it’s begun showing up in vendor docs and enterprise security playbooks. The list explicitly prioritizes prompt injection, “excessive agency” (agents with overly broad powers), and supply chain vulnerabilities in MCP servers and other tool layers. Cloud security and AI platform teams have started linking to the Top 10 as the baseline threat model for any workflow where agents can read untrusted data and trigger real system actions.

What changed. The final Agentic AI Top 10 moved from a niche security draft to the checklist enterprises and cloud providers are using to evaluate agent deployments, especially those wired into MCP and other tool-serving layers.

Why it matters. This effectively sets a bar: if your agent can act on external data or use tools, your buyers and security partners will expect crisp answers about how you mitigate each of these risk categories.

Builder takeaway. Map your current agent architecture—context flows, tool permissions, logging, and human-in-the-loop points—against the OWASP list now, and build those mitigations into your design docs and sales collateral or risk getting blocked at security review.
