Why it matters
The OWASP Top 10 for LLMs and Agents provides defenders a consolidated reference taxonomy of the vulnerability classes—prompt injection, tool abuse, supply-chain risks—that most affect deployed AI agent systems.
Alex Ewerlöf's cheat sheet walks through the OWASP Top 10 for LLM Applications (LLM01-LLM10) and OWASP Top 10 for Agentic Applications (ASI01-ASI10), grouping the 20 vulnerability categories into themes such as mixed instruction-and-data attack surface (prompt injection, jailbreaks), unpredictability and agentic threat surface, and reliability/cascading failures. Each section offers examples of bad implementations and pragmatic mitigations.
