This intermediate learning path dives deep into OWASP LLM07: Insecure Output Handling. You will explore how unvalidated or unsanitized LLM outputs can be weaponized to execute client-side attacks (like Cross-Site Scripting) or server-side compromises (like SSRF and Remote Code Execution) when integrated with downstream web applications and APIs. Through hands-on methodologies, real-world scenarios, and defensive countermeasures, you will learn how to secure the entire AI data pipeline from generation to rendering.
