Does this skill provide fixes for identified issues?

It provides a diagnostic report outlining what is wrong and why, helping developers implement the necessary security patches manually.

What kind of vulnerabilities can it detect?

It identifies common issues like wildcard origins, insecure header allow-lists, and improper handling of credentials that could lead to data breaches.

Can this skill check live API endpoints?

Yes, by providing a URL, the skill can fetch and analyze the live headers to ensure the remote service is correctly configured.

How do I validate a local CORS configuration file?

Ask Claude to 'Validate the CORS policy in [filename]'. The skill will read the file and provide a detailed report on any identified vulnerabilities.

Seguridad y Pruebas

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

Acerca de

The CORS Policy Validator skill empowers Claude to assess the security and correctness of web application and API access controls. By examining configuration files or fetching live headers from an endpoint, it detects common misconfigurations—such as overly permissive origins or insecure credential handling—that could lead to unauthorized cross-origin requests. This skill is an essential tool for developers and security engineers aiming to audit their systems and prevent data exposure through rigorous policy analysis.
