Introducing Blumira Briefings: Your Weekly Security News Download! 🔔

Staying on top of security news shouldn't be another full-time job.

That's why I’m thrilled to launch Blumira Briefings, our new weekly panel series where security experts break down the headlines you might have missed, and explain what they actually mean for your security practice! 🔒

What to Expect from Blumira Briefings 

Each week, I'll be joined by different Blumira experts (and sometimes special guests!) to:

• Share the top threats, suspects, and risks we're seeing across our detection and response platform
• Discuss significant security stories and what they mean for YOU
• Provide practical advice you can actually implement right away
• Keep it conversational, informative, and under 30 minutes (don’t mind the extra 14 seconds in this episode 🤫)

Critical Next.js Vulnerability 🛠️

We discussed the recent Next.js middleware vulnerability (CVE-2025-29927), rated critical severity with a CVSS score of 9.1. This flaw could allow attackers to bypass authorization checks by manipulating a specific header – not great!
