Detect prototype pollution vulnerabilities by executing targeted probes against JavaScript applications and analyzing the responses. This process identifies risks in both client-side and server-side environments, particularly within Node.js and browser stacks.

Prototype pollution is a JavaScript security vulnerability where object merging mechanisms improperly modify the prototype chain. Attackers can inject properties into base prototypes, potentially compromising application logic and security controls across client and server environments.

Yes, you can audit both client-side and server-side JavaScript for prototype pollution. The testing methods apply to Node.js server environments and browser client applications, executing probes to identify vulnerable object merging mechanisms.

Identify exploitation gadgets by analyzing the JavaScript application's response to injected prototype properties. This helps pinpoint specific code paths and functions that can be triggered and exploited through the discovered prototype pollution vulnerability.

Yes, understanding the JavaScript prototype chain and object merging mechanisms is required. This prerequisite knowledge is essential for effectively executing targeted probes and accurately interpreting application responses during a security audit.

The best way to scan a Node.js application is to execute targeted probes that test object merging mechanisms for prototype pollution risks. Analyzing the application's responses reveals vulnerable code paths and potential exploitation gadgets.
