BTCPay Server Has a Critical Security Flaw — And Hackers Are Already Exploiting It

WHY IT MATTERS

Think of BTCPay Server like setting up your own cash register that accepts Bitcoin — you control everything, but you're also responsible for keeping it secure. A critical flaw means there's a serious weakness in the software, like a broken lock on a store's back door. Worse, 'under active attack' means thieves have already found that broken lock and are trying to get in. If you're a merchant using BTCPay, updating your software is like changing that lock immediately. For the broader crypto community, this is a reminder that while controlling your own tools is empowering, it also means you have to stay on top of security updates — there's no IT department doing it for you.
