🛡️ Vulnerability Math: CVE vs. CVSS vs. EPSS

Ever wonder why some "Critical" bugs aren't fixed immediately? It’s all about Impact vs. Urgency.

Think of a Broken Lock on your front door:

  • CVE (The ID): The specific model number of that broken lock. It ensures everyone is talking about the same bug.
  • CVSS (The Severity): How much do you lose if a thief gets in? Jewelry (Score 10) or just a dirty rug (Score 2)?
  • EPSS (The Probability): Are there actually burglars in your neighborhood who know how to pick this specific lock?

The Takeaway:
A CVSS 9.8 means the impact is huge, but if the EPSS is 1%, the chance of it actually happening is low. Use CVSS to see how bad it could be, and EPSS to decide what to fix first.
