Payload Catalog

All payloads are stored as YAML files in payloads/catalog/. Each file covers one OWASP LLM Top 10 category.

Categories

LLM01 - Prompt Injection

Direct attempts to override system instructions or hijack model behavior through user input.

Examples:

  • Ignore previous instructions
  • Role-play overrides that strip safety guidelines
  • Instruction smuggling via nested prompts

LLM02 - Insecure Output Handling

Payloads that attempt to get the model to produce output that could be dangerous if consumed downstream by another system.

Examples:

  • Script injection in markdown output
  • JSON payload manipulation
  • HTML injection attempts

LLM06 - Sensitive Information Disclosure

Payloads designed to extract training data, system prompts, or confidential context the model should not reveal.

Examples:

  • System prompt extraction
  • Training data reconstruction
  • Configuration probing

LLM08 - Excessive Agency

Payloads that attempt to get the model to claim or exercise capabilities beyond its intended scope.

Examples:

  • False capability claims
  • Unauthorized action requests
  • Scope boundary violations
