Matt Schwager enhanced the github/codeql repository by expanding and refining CodeQL’s Ruby Net::HTTP analysis capabilities. He developed new features to detect connection reuse patterns and multiple HTTP methods, improving the visibility of NetHttpRequest nodes and supporting Net::HTTP.start usage in Ruby code. Using CodeQL and Ruby, Matt aligned tests and documentation to reflect these changes, broadening security coverage for network calls. He also refactored the NetHttp Request Detection Query, removing redundancies and clarifying relationships between request and connection nodes. This work reduced false positives and improved maintainability, demonstrating a thoughtful approach to static analysis and query accuracy.
