Still, it's the kind of data that could be very useful to scammers and identity thieves. According to a statement from Whalerock, Smith was the only one to access the data and the company was able to patch the problem relatively quickly, although Smith's Medium post was ultimately taken down to prevent wider exploitation of the bug. Still, it's a reminder to developers not to discount security the next time they're taking on a high-profile project.
