Moltbook, a social network for AI agents, was found to have a misconfigured Supabase database, exposing 1.5 million API keys, 35,000 email addresses, and private messages. The platform's founder had 'vibe-coded' the site, relying on AI to build it without writing a single line of code, which led to security oversights. The exposed data revealed that the platform had only 17,000 human owners behind the 1.5 million registered agents. The security issues were reported to the Moltbook team, who secured the database within hours.
