🚨 Attention: A Critical Next.js vulnerability

What Happened?

A massive vulnerability (CVE-2025-29927) was just found in Next.js, a popular framework for building web apps with React. This flaw, rated 9.1/10 for severity, lets attackers slip past security checks using a simple trick—a special header. It affects self-hosted Next.js apps (versions 11.1.4 to 15.2.2) that use middleware to protect pages, like admin dashboards. If unpatched, hackers could access restricted areas—yikes!

How Big Is It?

Pretty darn big! Millions of developers use Next.js, and this bug leaves tons of apps exposed. The good news? It’s fixed in version 15.2.3 and up. Please upgrade to newest version to stay safe!
