LAB 376 – Defending Node.js AI Applications from Prompt Injection (NEW)

Course Overview

Prompt Injection lets attackers hijack LLM behavior, leaking data or bypassing controls. Aligned with OWASP Top 10 LLM 2025 this lab provides hands-on experience in detecting and mitigating Prompt Injection. Learners will work with a vulnerable Node.js AI application, practicing techniques such as prompt isolation, input validation, least-privilege enforcement, and requiring human approvals for sensitive operations.

By the end of this skill lab, learners will be able to:

• Identify Prompt Injection vulnerabilities in Node.js AI applications
• Isolate system prompts from user inputs
• Validate inputs and enforce least-privilege controls
• Implement approval processes for sensitive actions
