Can I use this skill to check live websites?

Yes, you can provide a URL to an API endpoint, and the skill will fetch and analyze the CORS headers directly from the server response.

Does it support local configuration files?

Yes, it can read and validate local files like cors_policy.json to ensure they follow security best practices before you deploy them.

How does this improve my API security?

It prevents common mistakes like using wildcards in allowed origins or exposing sensitive headers, which are frequent targets for cross-origin attacks.

What does the CORS Policy Validator skill do?

It analyzes CORS settings in files or live headers to identify security risks, such as misconfigured origins or headers that could expose sensitive data.

セキュリティとテスト

Analyzes and validates Cross-Origin Resource Sharing (CORS) configurations to identify security vulnerabilities and ensure policy compliance.

The CORS Policy Validator skill empowers Claude to perform deep audits of your web application's Cross-Origin Resource Sharing policies. By leveraging the cors-policy-validator plugin, it automatically scans JSON configuration files or live API headers to detect misconfigurations, such as overly permissive origins or insecure headers, that could lead to unauthorized data access. It is an essential tool for developers and security engineers looking to harden their API infrastructure and protect sensitive user data from cross-origin attacks.
