SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Frontend applications often harbor security vulnerabilities and misconfigurations that expose users and data to risk. This Skill helps security teams and developers identify XSS, CSRF, DOM, CSP, and input-handling weaknesses, and to prepare actionable remediation guidance.

Core Features & Use Cases

  • Pattern-based scanning for common frontend vulnerabilities across vanilla JS, React, Astro, Twig templates, and Node.js frontends
  • Framework-specific risk checks, CSP validation, CSRF defenses, input handling review, and secure file upload guidance
  • Use Case: A multi-frontend project can be audited in one pass to surface critical issues and produce prioritized remediation plans

Quick Start

Run a security audit against a frontend repository to generate a prioritized remediation report.

Frequently Asked Questions about frontend-security

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I audit my React and vanilla JS codebase for XSS vulnerabilities?

To audit frontend code for XSS, run a pattern-based security scan across your React and vanilla JS files to identify unsafe input handling and DOM manipulation. The tool evaluates framework-specific risks and generates a prioritized remediation report.

What is the best way to check Content Security Policy and CSRF defenses in a frontend project?

The best way to check CSP and CSRF defenses is to perform a targeted security audit that evaluates your policy configurations and token validation mechanisms. This surfaces misconfigurations and produces actionable remediation guidance for your frontend application.

Does this frontend security audit support Astro and Twig templates?

Yes, the frontend security audit supports Astro and Twig templates. It performs framework-specific risk checks across multiple environments including Astro, Twig, React, Node.js, and vanilla JS, allowing a multi-frontend project to be audited in one pass.

How do I review frontend dependency risks and secure file upload handling?

You can review dependency risks and secure file upload handling by executing a comprehensive security audit workflow. This scans your codebase for vulnerable dependencies and evaluates input handling mechanisms, resulting in a prioritized plan to secure your application.

Why do I need a pattern-based scan instead of just manual code review for DOM vulnerabilities?

A pattern-based scan is needed because it deterministically identifies DOM vulnerabilities across large codebases faster than manual review. It applies standardized risk checks for unsafe DOM manipulation and input handling, ensuring consistent detection and actionable remediation reporting.
