Short summary

Prompt injection is OWASP's #1 LLM vulnerability for the second year running, exploiting models' inability to distinguish system instructions from user-supplied data. Five critical attack vectors are documented: cross-model injection, RAG poisoning, agent hijacking, context overflow, and memory poisoning. Organizations building AI systems must understand these threats to prevent data leakage, unauthorized actions, and compliance violations.

• •Prompt injection ranked LLM01 on OWASP Top 10 for 2025 (second consecutive year)
• •Five exploit patterns detailed: cross-model chains, RAG supply-chain poisoning, agent hijacking, context overflow, memory poisoning
• •Critical mitigation priority for product teams integrating LLMs into customer-facing or internal systems
