Skill UI

Guides systematic detection and exploitation of cross-site scripting and HTML injection flaws, covering stored/reflected/DOM vectors, payload crafting, and remediation advice for web security assessments.

This skill acts as a comprehensive security scanner specializing in detecting Cross-Site Scripting (XSS) vulnerabilities in client-side code. It performs static analysis across React, Vue, Angular, and vanilla JavaScript, specifically identifying unsafe practices like direct HTML manipulation (innerHTML), raw rendering (v-html), and insecure URL handling. Use it when auditing frontend code for security flaws and needing best practices for secure coding.

A comprehensive guide covering essential security practices for developing Obsidian plugins. Learn how to safely handle sensitive credentials (avoiding data.json), implement robust input validation, prevent Cross-Site Scripting (XSS), secure URI handlers, and adhere to modern Electron and Obsidian guidelines for data privacy and system integrity.

Guides systematic detection and exploitation of cross-site scripting and HTML injection flaws, covering stored/reflected/DOM vectors, payload crafting, and remediation advice for web security assessments.

A comprehensive guide for web security professionals detailing advanced techniques to bypass Content-Security-Policy (CSP) headers. It covers exploiting weaknesses such as unsafe-inline/unsafe-eval, JSONP endpoints, base-uri, and nonce/hash gaps. Used during penetration testing or bug bounty hunting to achieve Cross-Site Scripting (XSS) or data exfiltration even when CSP is implemented.

A comprehensive guide for performing systematic security assessments on web applications. Following the OWASP Web Security Testing Guide (WSTG), this process identifies critical vulnerabilities such as broken authentication, authorization flaws (IDOR), SQL injection, and Cross-Site Scripting (XSS). The workflow covers reconnaissance, mapping, and advanced testing techniques using tools like Burp Suite and sqlmap, ensuring deep coverage beyond automated scanner capabilities. Ideal for pre-production security validation and compliance audits.

A detailed methodology for identifying Cross-Site Scripting (XSS) vulnerabilities across web applications. It guides systematic testing for Reflected, Stored, and DOM-based XSS, covering payload bypass, output encoding evaluation, and assessing Content Security Policy (CSP) protection. Essential for OWASP WSTG testing and client-side security audits.

A comprehensive guide detailing how to identify and validate Cross-Site Scripting (XSS) vulnerabilities using Burp Suite's advanced tools (Repeater, Intruder, DOM Invader). This methodology covers reflected, stored, and DOM-based XSS, and includes strategies for bypassing security filters and Content Security Policy (CSP), making it essential for web application penetration testing and bug bounty programs.

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.

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.

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.

This skill enables comprehensive static analysis of frontend codebases to detect Cross-Site Scripting (XSS) vulnerabilities. It identifies unsafe DOM manipulation, improper sanitization, and injection points across frameworks like React, Vue, and Angular. Use it to secure client-side applications against critical security risks.
