Detect and exploit DOM-based XSS vulnerabilities by auditing JavaScript for tainted data flow from controllable sources to dangerous sinks, with payloads and bypass techniques for client-side testing.

Detect and exploit JavaScript prototype pollution vulnerabilities on both client-side and server-side applications to achieve XSS, RCE, and authentication bypass through property injection.

Reverse-engineers custom JavaScript-based WASM virtual machines and risk-control engines by identifying DSL VM patterns, extracting opcodes, analyzing constant tables, and tracing exported functions through static analysis and runtime injection.

Stored XSS (persistent XSS) occurs when attacker-supplied input is saved server-side and later rendered unencoded to other users. Common injection points include profile fields, comments, forum posts, file upload filenames, and application logs. Detect via PHP `$_GET/$_POST/$_REQUEST/$_FILES`, ASP `Request.Form`, JSP `request.getParameter`, and BeEF hook injection. Tools: Burp Suite, OWASP ZAP, BeEF, PHP Charset Encoder, Hackvertor.

Provides exact payloads and bypass techniques for every PortSwigger DOM-based vulnerability lab variant, including zero-day extensions and blue team detection strategies.
