CodeRabbit Security: How AI Detects Vulnerabilities

Every pull request is a potential entry point for a security vulnerability. A developer adds a database query with string interpolation instead of parameterized binding. Another hardcodes an API key in a configuration file that was supposed to stay local. A third accepts user input and passes it directly to a subprocess call. These are not theoretical risks - they are the exact patterns that lead to the breaches you read about in security incident reports. The question is whether your code review process catches them before they reach production. CodeRabbit has built security vulnerability detection into its AI-powered pull request review. When a PR is opened, CodeRabbit does not just look at code style and logic - it analyzes data flow, identifies dangerous patterns, and flags security issues with contextual explanations of why they matter and how to fix them. This guide covers exactly what CodeRabbit catches, what it misses, how to configure it for security-focused reviews, and how i
