SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill centralizes and standardizes security testing for web applications to identify and validate common vulnerabilities such as XSS, CSRF, SQL injection, authentication/authorization flaws, insecure headers, and improper session management before production rollout.

Core Features & Use Cases

  • Security header validation: Checks CSP, X-Frame-Options, X-Content-Type-Options, HSTS and other important headers.
  • Browser and API tests: Playwright-style browser tests for XSS and CSRF, API-level checks for authorization and SQL injection, and file upload security scenarios.
  • Authentication & authorization checks: Password policy enforcement, account lockout behavior, session timeout simulation, and RBAC verification.
  • Use Case: Run this Skill against a staging instance of a legal case management platform to validate input sanitization, secure cookie attributes, CSRF token handling, and that sensitive user data is not exposed via APIs.

Quick Start

Run the security-testing-specialist checklist against your staging site to execute automated header, XSS, CSRF, SQL injection, authentication, authorization, file upload, rate limiting, and HTTPS enforcement checks.

FAQPage Schema
How do I validate security headers and secure cookie attributes in my web application?

To validate security headers like CSP, HSTS, and X-Frame-Options, this Skill inspects HTTP responses and asserts secure cookie attributes alongside HTTPS enforcement during automated security testing.

Can I use Playwright to automate XSS and CSRF security testing?

Yes, you can use Playwright-style browser automation to execute XSS and CSRF security testing, simulating file uploads, authentication flows, and rate-limiting scenarios against staging instances.

What is the best way to check for broken access control and RBAC flaws in APIs?

The best way to check for broken access control and RBAC flaws is through API request simulation that verifies session management, account lockout behavior, and authorization boundaries across different user roles.

Does this security testing approach work for both web applications and APIs?

Yes, this security testing approach works for both web applications and APIs, guiding browser automation for client-side XSS and CSRF alongside HTTP request tooling for API-level SQL injection and authorization checks.
