Brakeman is a static analysis security tool and scanner specifically designed for Ruby on Rails source code. It identifies common security vulnerabilities, such as injection and cross-site scripting, by analyzing the application codebase without executing the application.
The tool functions as a security auditor that detects mass assignment risks and template vulnerabilities. It evaluates the final output of rendered views and identifies unrestricted assignment patterns that could allow unauthorized modification of model attributes.
The system provides vulnerability management through the use of confidence-level scoring, warning suppression for false positives, and the ability to compare current scans against previous reports to identify new or resolved flaws. It supports exporting findings in multiple formats and integrating security checks into development pipelines.
