The real reason Tea got hacked (it's NOT vibe coding)
Source: YouTube · Theo - t3․gg · published Jul 31, 2025 · 24:51
The Tea app data breach was caused by poor architectural decisions where user verification files were stored in a publicly accessible Firebase bucket, enabling hackers to access hundreds of thousands of photos and IDs 3:38-3:413:56-3:59.
Key Takeaways:
• The breach occurred when hackers exploited an exposed Firebase endpoint to obtain an index of all file URLs, making it a legitimate hack despite the bucket being public 7:00-7:098:02-8:08
• Firebase's design allows direct database access without proper API layers, encouraging insecure development practices 12:04-12:0716:56-17:00
• Mobile developers often avoid building proper server-side code, leading to these security vulnerabilities 10:30-10:3822:00-22:06
• The solution requires writing proper data access code with built-in security checks rather than exposing databases directly 23:36-23:41
This hack demonstrates the dangers of prioritizing development convenience over security in application architecture.

The tea hack is an absolute nightmare. If you haven't been keeping up, it's one of the biggest stories right now. Tea is an app for women to share information about men that they've dated. I don't want to go into the details of how we feel about this. I'm sure that we all have opinions. What we're here to talk about is the absurd hack that occurred to them. And yes, I am calling it a hack. I know people are going to argue against it. They're wrong. We'll go in detail on what's going on here. I really didn't want to cover this, though. There are lots of other YouTubers that do security stuff really well. But the more I've looked into it, the more I realize this isn't a traditional security issue or exploit. This is bad design decisions that have caused for absurd amounts of data to leak thr…
