While scores are a good way to bring this stuff to people's attention, I wouldn't use them to enforce business processes. There's a good chance your code isn't even affected by this CVE even if your security scanners all go full red alert on this bug.
Surprised there isn’t more talk about a solution like this or something and more downplaying CVSS.
Downplaying CVSS alone can smell a little like PR talk even however unintentional.
