What problem does it solve?

This Skill addresses the security risk of overly permissive Cross-Origin Resource Sharing (CORS) policies, which can expose sensitive data and allow unauthorized actions by malicious websites.

Core Features & Use Cases

  • Detects insecure CORS configurations: Identifies wildcard (*) or reflected Origin headers.
  • Provides secure alternatives: Offers examples of strict allowlists for trusted origins.
  • Use Case: Reviewing an API's response headers to ensure that Access-Control-Allow-Origin is not set to * or reflecting an untrusted client origin, thereby preventing potential data breaches.

Quick Start

Review the CORS configuration for the current project to ensure it follows security best practices.
