Why it matters

The OWASP LLM Top 10 provides defenders a shared taxonomy for the runtime attack surface of LLM and agentic applications, though this piece is a vendor-authored explainer rather than a new finding or exploit.

Openlayer's guide summarizes the 2025 OWASP Top 10 for LLM applications, explaining why LLM systems need dedicated security testing and detailing risk categories such as prompt injection, excessive agency, system prompt leakage, poisoned vector stores, unbounded consumption, and vector/embedding weaknesses. It argues that static code analysis and CVE scanning miss inference-time attacks and that agentic systems require session-level testing, while mapping OWASP results to EU AI Act obligations and promoting Openlayer's coverage.
