Can it fix the CORS issues automatically?

While it focuses on validation and reporting, it provides specific code examples for remediation which you can then instruct Claude to implement in your codebase.

How does this skill check my CORS policy?

It analyzes your configuration files or fetches headers from a live endpoint to identify vulnerabilities like wildcard origins, insecure protocols, or unauthorized credential exposure.

Is this skill compliant with security standards?

The skill uses heuristics based on industry standards such as OWASP and CWE to identify security gaps and compliance issues.

Does it work with local configuration files?

Yes, it can read and validate JSON, YAML, or application-specific configuration files stored within your project directory.

Security & Testing

Validates Cross-Origin Resource Sharing (CORS) configurations to identify security vulnerabilities and misconfigurations.

About

The CORS Policy Validator skill empowers Claude to perform automated security audits on your web applications and API endpoints. By analyzing static configuration files or fetching live headers from remote URLs, it identifies dangerous patterns such as wildcard origins, insecure protocols, and unauthorized credential exposure. It provides developers with a comprehensive security report including prioritized findings and actionable remediation steps to ensure compliance with modern security standards like OWASP.
