This module introduces Insecure Output Handling (OWASP LLM07), a critical vulnerability where applications blindly trust and execute content generated by Large Language Models. You will learn why LLM outputs must be treated as untrusted user input, how downstream components (browsers, databases, OS shells) are compromised by unsanitized AI responses, and the foundational principles of context-aware output encoding and sandboxing.
