Prompt Injection / LLM
Probes for LLM-backed features (chat, RAG, agents). Start with a benign marker to prove the model follows injected instructions, then escalate to system-prompt leak, insecure output handling (output → XSS/SSRF/command sink), and tool/agent abuse. Indirect probes go inside data the model ingests (docs, pages, emails, filenames). Keep PoCs benign - use OAST callbacks, never real exfil. See the /bypasses/ ai-guardrails sheet.

Identify the parser, sink, encoding, and expected non-vulnerable behavior before choosing a sample. Prefer non-destructive markers.
