How Your Webpack Source Maps Are Leaking Production Secrets

Lucas and Luna reveal how misconfigured source maps in production builds leak internal code paths, API endpoints, and even credentials to anyone who opens browser dev tools. They walk through a real incident where a major e-commerce site exposed its entire internal admin panel structure via a .map file served from their CDN. The episode covers how to audit your own source map exposure, the difference between hidden-source-map and nosources-source-map, and why Webpack's default settings are dangerously permissive. You'll learn a single-line config change that stops the leak cold, plus how to verify the fix with curl. No scaremongering — just concrete steps to lock down what should never leave your build server. #Webpack #SourceMaps #WebSecurity #Frontend #JavaScript #DevTools #ProductionSecurity #WebpackConfig #HiddenSourceMap #NosourcesSourceMap #CDNLeak #CodeExposure #SecurityAudit #Technology #FexingoBusiness #BusinessPodcast #WebDevPodcast #FexingoTech Keep every episode free: buymeacoffee.com/fexingo
