The OWASP Top 10 for LLM Applications 2026 shifts focus from preventing models from being fooled to designing systems that can withstand such failures. This new approach treats LLMs as actors with tools and execution rights, rather than simple components, reframing security risks like prompt injection and excessive agency as stages in a kill chain. The updated list incorporates real-world incident data alongside practitioner votes, with key changes including the rise of Excessive Agency and Unbounded Consumption, and the renaming of System Prompt Leakage to Hidden Context Exposure.
