VulnAPI: An API Security Vulnerability Scanner

VulnAPI is an Open-Source DAST designed to help you scan your APIs for common security vulnerabilities and weaknesses.

By using this tool, you can detect and mitigate security vulnerabilities in your APIs before they are exploited by attackers.

Use this action to scan your project for vulnerabilities with VulnAPI.

Vulnerabilities Detected

All the vulnerabilities detected by the project are listed at this URL: API Vulnerabilities Detected.

More vulnerabilities and best practices will be added in future releases. If you have any suggestions or requests for additional vulnerabilities or best practices to be included, please feel free to open an issue or submit a pull request.
