Skill UI

A comprehensive checklist and methodology for testing Cross-Site Scripting (XSS) vulnerabilities. Covers all major types, including Stored, Reflected, DOM, and Blind XSS, along with advanced techniques like CSP bypass, polyglot payloads, and event handler injection. Essential for web application security testing and bug bounty hunting to identify and mitigate malicious script injection risks.

Logic Lens is an advanced AI skill that performs deep, formal logic-driven code review. Unlike standard linters, it analyzes code for complex issues like race conditions, security vulnerabilities (SQL injection, XSS), type safety flaws, and algorithmic errors across 9 critical risk categories. It is ideal for pre-merge PR reviews, auditing sensitive code paths, and refactoring complex business logic.

A comprehensive playbook for expert-level Android application security testing. It covers advanced exploitation techniques, including SSL pinning bypass (using Frida/Objection), detecting component exposure (activities, providers, services), and exploiting WebView vulnerabilities (RCE, XSS). Essential for authorized mobile penetration testing assessments.

A detailed playbook covering CRLF (Carriage Return Line Feed) injection techniques. This exploit targets insecure handling of user input within HTTP response headers (e.g., Location, Set-Cookie) or log files. It demonstrates advanced attacks like response splitting, XSS escalation via double CRLF, cache poisoning, and session fixation, essential for deep security testing.

A powerful technique used when full XSS is blocked by CSP, sanitizers, or WAFs, but HTML injection is possible. It leverages unclosed HTML tags (like <img> or <link>) to capture and exfiltrate sensitive page data (CSRF tokens, session IDs, form values) by forcing the browser to include the subsequent content in a request URL.

This router serves as the main entry point for comprehensive injection testing. It helps security professionals classify dangerous input flows—such as XSS, SQLi, SSRF, XXE, etc.—by determining the final sink or interpreter (e.g., browser context, database, XML parser, shell). Use it when unsure which specific injection vector to prioritize.

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.

An expert-level playbook covering non-obvious XSS techniques, advanced payload selection across various sinks (DOM, SVG, HTML attributes, JavaScript), and sophisticated defense bypass strategies. Use this guide for real-world penetration testing, including WAF bypass, CSP bypass, HttpOnly bypass, and XS-Leaks side channel exploitation. It assumes deep knowledge of web vulnerability mechanics.

A powerful PreToolUse hook designed to act as a safety net during code writing sessions. It automatically scans both file paths and content for 12 common security anti-patterns, including SQL injection, XSS, command injection (Node.js/Python), and unsafe deserialization. It blocks the writing operation and provides immediate warnings, ensuring adherence to secure coding practices when handling sensitive code like authentication or payment logic.

This skill enforces a rigorous data validation protocol by establishing hard boundaries at every point data enters the system (API requests, user input, environment variables, webhooks, etc.). It mandates a four-phase process: detection, trust classification, mandatory filtering (schema validation, sanitization, type checking), and final verification. This prevents untrusted data from reaching core business logic, mitigating risks like SQL injection and XSS.

A comprehensive guide covering essential security best practices for Django applications. It details how to implement robust authentication, granular authorization (RBAC), and crucial security settings like CSRF/XSS protection, HSTS, and secure environment configuration to prevent common vulnerabilities in production deployments.
