Web App Pen Testing in an Angular Context

This post provides practical guidance for penetration testing Angular 2+ applications, outlining how modern framework safeguards limit DOM-based injection by default, while highlighting developer misconfigurations (template injection, disabled sanitization, direct DOM use), backend/API risks (validation gaps, IDOR), and JWT session weaknesses. It details hands-on techniques to improve testing—using Burp Suite match/replace to neutralize enableProdMode, finding obfuscated functions via unique strings, removing SRI integrity attributes to permit in-flight script modification, and leveraging ng.probe() for component inspection—alongside considerations for CSP and SSR.
