What does the CORS Policy Validator skill do?

It analyzes Cross-Origin Resource Sharing (CORS) settings to ensure they are secure and correctly implemented according to security best practices.

How do I trigger this skill in Claude Code?

You can trigger the skill using prompts such as 'validate CORS policy', 'check CORS headers', or 'analyze my API's CORS configuration'.

Why is CORS validation important for security?

Misconfigured CORS policies can allow malicious websites to make unauthorized requests to your API, potentially leading to data breaches and CSRF attacks.

Can it check live API endpoints?

Yes, the skill can fetch and analyze headers directly from a specified URL to identify potential real-time security risks.

Does it support local configuration files?

Yes, you can ask Claude to read and validate local files like cors_policy.json or server configuration snippets to check for errors.

Security & Testing

Validates Cross-Origin Resource Sharing (CORS) configurations to identify security vulnerabilities and ensure robust web application protection.

About

The CORS Policy Validator skill empowers Claude to perform deep security assessments of Cross-Origin Resource Sharing settings. By utilizing the specialized cors-policy-validator plugin, it analyzes headers and policy files to detect common misconfigurations, such as overly permissive origins or insecure credential handling. This skill is essential for developers and security engineers who need to audit API endpoints, troubleshoot cross-origin communication issues, and prevent unauthorized data access in web environments.
