OWASP Top 10 for LLM Applications 2025 — Plain English Explanation with Real Examples

TLDR: Three years ago "OWASP Top 10 for LLM Applications" would have been a meaningless phrase. Today it's the most important document in AI application security — a consensus from hundreds of developers, researchers, and security professionals on the ten risks most likely to cause real damage in real AI products. This post translates all ten into plain English with concrete examples. Save it. Share it with your engineering team. Use it as a checklist the next time someone asks "did we think about security?" before shipping an AI feature. Why This List Exists The original OWASP Top 10 for web applications has been the industry's shared language for application security since 2003. When LLMs started appearing in production systems at scale, the security community recognised that the threat model was different enough to need its own list — some traditional risks still apply, but in new ways, and entirely new categories of vulnerability exist that have no parallel in classic web security.
