How Your NextJS App Is Leaking Data Via Server Actions

Lucas and Luna dig into a quietly pervasive issue in modern NextJS apps: server actions that inadvertently expose internal API endpoints, database schemas, or even PII through client-server boundary leaks. They walk through a real-world example from a fintech startup's recent security audit, showing how a simple form action can leak your entire Prisma schema, and explain the one-line fix most teams miss. Touching on framework design trade-offs, Vercel's stance, and the broader trend of server components blurring the line between client and server, this episode gives you a concrete audit checklist for your own codebase. #NextJS #ServerActions #WebSecurity #DataLeakage #ReactServerComponents #Vercel #Prisma #APILeak #FrontendSecurity #WebDevelopment #Technology #FexingoBusiness #BusinessPodcast #LucasAndLuna #WebDevPodcast #Fintech #CodingBestPractices #BundleAnalysis Keep every episode free: buymeacoffee.com/fexingo
