セキュリティとテスト

Analyzes web applications to identify and remediate Cross-Site Request Forgery (CSRF) vulnerabilities across all endpoints.

概要

The CSRF Protection Validator skill empowers Claude to perform deep security audits focused on Cross-Site Request Forgery. It systematically examines application endpoints to detect missing protections, validates the implementation of synchronizer tokens and double-submit cookies, and audits SameSite cookie attributes. By providing detailed reports and remediation steps, it helps developers secure state-changing operations and maintain a robust security posture against unauthorized web-based attacks.
