Worked on the github/codeql repository to add support for detecting vulnerabilities in Vercel serverless function handlers, focusing on both modern and legacy request and response types. Leveraged JavaScript and TypeScript to extend the framework model, enabling CodeQL to recognize default-exported handlers typed as VercelRequest and VercelResponse, as well as legacy @now/node aliases. Enhanced documentation and test coverage by clarifying QLDoc and providing fixtures for end-to-end detection of common JavaScript vulnerabilities. Addressed quality feedback by refining framework naming, correcting spelling, and ensuring explicit sync and async handler support, contributing to improved security analysis and maintainability within the codebase.
Concise monthly summary focusing on the CodeQL repository's work in April 2026, emphasizing business value and technical achievements.
