About This Skill
What it does
The cors-audit skill performs a Cross-Origin Resource Sharing (CORS) audit on specified URLs. It checks if resources are properly configured to allow cross-origin requests, identifying potential security vulnerabilities and compliance issues. The tool provides detailed reports outlining allowed origins and any detected misconfigurations.
When to use it
- Security Assessment: Before deploying a web application that relies on cross-origin resource sharing, verify its CORS configuration.
- Troubleshooting API Access: Diagnose why your frontend application is unable to access an API due to CORS restrictions.
- Compliance Checks: Ensure adherence to security best practices and relevant regulations regarding cross-origin requests.
- Identifying Misconfigurations: Quickly identify unintentional or overly permissive CORS settings that could expose sensitive data.
Key capabilities
- CORS configuration auditing
- Detailed reporting of allowed origins
- Identification of potential vulnerabilities related to CORS misconfiguration
Example prompts
- "Audit the CORS configuration for
https://example.com/api." - "Check if
https://mywebapp.netallows requests fromhttps://frontend.app." - "Perform a full CORS audit on all endpoints listed in this file: [file contents]"
Tips & gotchas
The skill requires the ability to make HTTP requests, so ensure your AI agent has appropriate network access and permissions. The accuracy of the results depends on the target server's response headers; some servers may not provide complete or accurate CORS information.
