Good to know
- CVSS measures severity, not risk. A critical bug on a system that is not exposed can wait behind a medium one that is.
- CVSS 4.0 splits impact into the vulnerable system and the systems beyond it, and adds Attack Requirements; most new advisories publish both 4.0 and 3.1 vectors.
- Share the vector, not just the number: two 7.5s can be very different problems.
