Security & Testing

Identifies Cross-Site Request Forgery (CSRF) vulnerabilities by auditing security mechanisms like tokens, cookies, and SameSite attributes.

About

The CSRF Security Validator skill empowers Claude to perform automated security audits of web applications, specifically targeting Cross-Site Request Forgery risks. It analyzes application endpoints to detect missing protections, validates the implementation of synchronizer tokens and double-submit cookies, and checks SameSite cookie attributes. This skill is essential for developers and security engineers who need to assess an application's security posture, generate remediation reports, and ensure all state-changing operations are shielded from malicious cross-site attacks.

Key Features

Validation of CSRF tokens and double-submit cookie patterns
Identification of attack vectors for unprotected state-changing operations
Endpoint vulnerability analysis for missing CSRF guards
Detailed security report generation with remediation steps
884 GitHub stars
Auditing of SameSite cookie attributes and origin validation

Use Cases

Auditing a web application's API for CSRF protection gaps before deployment
Generating comprehensive security reports for compliance and vulnerability management
Verifying SameSite cookie configurations to prevent unauthorized cross-site requests
