NEW! Data443 Acquires Vaikora – Real-Time AI Runtime Control & Enforcement for AI Agent
The OWASP Top 10 for Agentic Applications, published in 2026, is the security community’s first formal ranking of risks specific to AI agents. It complements the existing OWASP Top 10 for LLM Applications by focusing on the action layer rather than the language-model layer.
Until OWASP shipped this list, every vendor and every security team carried its own informal taxonomy. The list provides a common vocabulary. Procurement teams can require coverage of specific risks. Auditors can ask vendors to map their controls. Security tooling vendors can advertise which risks they address.
The top ten in the 2026 release: prompt injection (direct and indirect), sensitive information disclosure, supply-chain compromise, data and model poisoning, improper output handling, excessive agency, system prompt leakage, vector and embedding weaknesses, misinformation, and unbounded consumption.
The list maps to product categories. AI runtime control addresses excessive agency and improper output handling. Prompt injection defenses address the top-ranked risk. AI observability contributes to misinformation detection and supply-chain monitoring. Red teaming validates coverage across the full list.
A finance team deploying an autonomous invoice-paying agent maps each top-ten risk to a control. Excessive agency becomes a policy that caps single-invoice payments at 5,000 USD without human review. Improper output handling becomes a sanitization rule on the agent’s response. Prompt injection becomes a Vaikora policy with the prompt-injection content module enabled. A second example: a security vendor’s RFP response explicitly references the OWASP Agentic Top 10 and shows which of its controls map to which risks, allowing the buyer to compare across vendors on a common scale.
The LLM list focuses on the language model layer. The agentic list focuses on agents that take actions. Both are useful; agentic teams reference both.
OWASP lists are community-maintained guidance, not enforceable standards. Major frameworks (NIST AI RMF, ISO/IEC 42001) reference OWASP lists but they are not themselves regulation.
Vaikora addresses risks 1, 5, 6, 7, and 9 directly through runtime control and the audit chain. Risks 2, 3, 4, 8, and 10 are typically handled by adjacent products that integrate with Vaikora through observability and policy hooks.
OWASP publishes the list on its website with risk descriptions, common attack patterns, and mitigation guidance. Each item includes worked examples from real-world agent deployments.
