CFRipper is a library and command-line interface (CLI) security analyzer designed for AWS CloudFormation templates. The tool analyzes CloudFormation templates to identify potential security vulnerabilities and misconfigurations before deployment to AWS cloud environments. The analyzer includes built-in security rules that check for common issues such as overprivileged IAM roles, wildcard principals, and cross-account trust configurations. Users can extend the tool's functionality by creating custom compliance checks through a plugin system. CFRipper operates as both a standalone CLI tool and a Python library that can be integrated into existing workflows. The CLI supports multiple output formats and includes features like template resolution for comprehensive analysis. The tool helps prevent the deployment of insecure AWS resources by identifying security issues during the infrastructure-as-code review process.
