OWASP Top 10 for Agentic Applications

The OWASP Top 10 for Agentic Applications, published by the OWASP GenAI Security Project on 9 December 2025, names the ten most critical risks for AI agents, numbered ASI01 to ASI10: goal hijack, tool misuse, identity and privilege abuse, agentic supply chain, unexpected code execution, memory and context poisoning, insecure inter-agent communication, cascading failures, human-agent trust exploitation and rogue agents.

The ten risks

ID Risk What it means
ASI01 Agent Goal Hijack The agent’s objective is redirected, usually by injected instructions
ASI02 Tool Misuse The agent uses legitimate tools in harmful ways
ASI03 Identity & Privilege Abuse The agent’s access is used to reach what the user could not
ASI04 Agentic Supply Chain Vulnerabilities Compromised tools, plugins, models or other agents
ASI05 Unexpected Code Execution The agent writes or runs code that does harm
ASI06 Memory & Context Poisoning Stored context is altered to influence later decisions
ASI07 Insecure Inter-Agent Communication Messages between agents are spoofed, read or changed
ASI08 Cascading Failures One agent’s error or compromise spreads through others
ASI09 Human-Agent Trust Exploitation People are manipulated into approving harmful actions
ASI10 Rogue Agents Agents acting outside their intended scope

Using it in a review

For each agent, list what it can reach and what it can do, then walk the ten risks against that list. The useful questions are concrete: which tools can this agent call, with whose permissions, what happens if its input is hostile, and who has to approve before anything irreversible happens.

How HYDN tests it

AI red teaming runs goal-driven campaigns against agents, multi-agent systems and human-in-the-loop workflows, using the HYDN AI Attack Engine and tailored scenarios. Findings are mapped to this list.

Questions

Frequently asked questions

What makes an application 'agentic'?

It plans, uses tools, remembers context and acts with some autonomy, often alongside other agents. That gives it ways to cause harm that a chatbot answering questions does not have.

Which risks matter most?

It depends on what your agents can reach. Agents with access to money, customer data or production systems make tool misuse, privilege abuse and goal hijack the priorities.
