Some Supabase customers are publicly exposing reams of people’s data to the web
Thousands of databases hosted by development platform Supabase are exposing people’s sensitive information to the public web, new security research by cybersecurity firm UpGuard has found. UpGuard told TechCrunch that it found around 16,000 databases on which some degree of personal data was exposed while they were hosted by Supabase, which allows web and app developers to store and run their databases. Supabase earlier this year reached a $10 billion valuation, thanks to a rise in developers hosting their vibe-coded apps on the platform.
