Prompt Injection Remains Biggest LLM Risk, Despite Limited Incidents

The OWASP Top 10 for LLM Applications (v3) ranks and explains the primary security threats posed by generative AI—placing prompt injection first—alongside sensitive information disclosure, excessive agency, misinformation, and unbounded consumption; the report emphasizes designing systems assuming instruction boundaries can be bypassed and recommends mitigations such as constraining model outputs, minimizing tool functionality and permissions, grounding outputs in authoritative sources, applying quotas, and sandboxing.
