This skill guides the detection and exploitation of JavaScript prototype pollution vulnerabilities. It covers both client-side (DOM XSS) and server-side (RCE, Auth Bypass) attacks by injecting properties into Object.prototype using keys like `__proto__`. Use this when assessing APIs that deep-merge or clone user-controlled JSON data, or for general web application security testing.

This skill details how to execute HTTP Parameter Pollution (HPP) attacks. HPP exploits differences in how web applications and Web Application Firewalls (WAFs) process duplicate parameters within a single request (e.g., query strings or POST bodies). It is crucial for penetration testing to bypass input validation, WAF rules, and uncover parameter parsing inconsistencies in APIs and web forms.

This guide details advanced techniques for bypassing Web Application Firewalls (WAFs). It covers methods such as payload obfuscation, advanced URL encoding, HTTP method manipulation (PUT, PATCH, etc.), parameter pollution, and utilizing specialized tools like SQLMap tamper scripts to smuggle exploit payloads (e.g., SQLi, XSS) past perimeter security controls. Essential for penetration testing and red team engagements.

This skill provides comprehensive guidance on correctly configuring Model Context Protocol (MCP) servers within Claude Code. It details the critical concepts of configuration scope (user vs. project) and outlines best practices to prevent context pollution across different coding sessions. Users learn how to safely add, remove, and clean up MCP settings using specific JSON files, ensuring a stable and efficient development environment.

This skill provides a comprehensive operational checklist for identifying and exploiting HTTP Parameter Pollution (HPP) vulnerabilities. It details how various web technologies (ASP.NET, PHP, Python, etc.) handle duplicate parameters differently (e.g., first-wins, last-wins, concatenation). Use this skill during penetration testing to discover flaws in parameter parsing, which can lead to bypassing WAFs, performing logic manipulation, or achieving unauthorized access.

HTTP Parameter Pollution (HPP) occurs when a single request contains multiple instances of the same parameter key. Different components in the request path (e.g., WAFs, proxies, application frameworks) may parse these duplicate keys using different rules (first value, last value, array join). This skill teaches how to exploit these discrepancies to bypass security checks, execute SSRF, or manipulate business logic.

A comprehensive playbook detailing NoSQL injection techniques, moving beyond traditional SQLi. Covers deep vulnerabilities in MongoDB, including operator injection, login bypass, blind data extraction using regex, and $where execution. Also includes attacks specific to Redis, CouchDB, and general API parameter pollution.

This comprehensive playbook details advanced techniques for detecting Prototype Pollution vulnerabilities in JavaScript environments (Node.js and browser). It covers various attack vectors, including using `__proto__` and `constructor.prototype` paths, and provides black-box testing payloads for JSON parsing, query string merging, and deep object assignment. Use this when analyzing applications for potential Remote Code Execution (RCE) or unintended property leakage via object merging sinks.

This advanced playbook covers escalating prototype pollution into Remote Code Execution (RCE) and Cross-Site Scripting (XSS). It details exploitation techniques across various environments, including Node.js child_process, EJS, Pug, Handlebars, and client-side libraries like jQuery and Lodash. It is designed for security researchers and penetration testers to systematic locate and exploit deep merge sinks and framework gadgets.

A comprehensive playbook detailing advanced methods to bypass Web Application Firewalls (WAFs) when standard injection payloads (SQLi, XSS, RCE) are blocked. Techniques include encoding (URL, Unicode, Hex), protocol abuse (HTTP/2, chunking), parameter pollution, and path normalization tricks, allowing security professionals to test robust application defenses.

This comprehensive guide provides best practices for designing and presenting scientific experiments for high-impact academic journals. It covers structuring research around clear Research Questions (RQs), selecting strong and fair baselines, ensuring statistical rigor (mean ± standard deviation, significance testing), performing detailed ablation studies, and preventing common issues like data leakage and evaluation pollution. It is essential for authors aiming to validate complex computational findings.

This comprehensive guide helps authors determine the suitability and necessary framing for research related to environmental contamination. It mandates moving beyond simple pollutant detection, requiring rigorous evidence to connect contaminants to their fate, transport, and demonstrable ecological or human health impact. Essential for method validation, QA/QC, and scientific rigor.
