CVEs alert end users that they need to take action to apply updates. That's relevant when a specific npm package contained a known vulnerability. It's not relevant when the npm server contained a known vulnerability. There's nothing a user of npm can do to update the npm server.
CVEs don't just mean "this is a big security problem".
Isn't this the biggest security flaw in the package ecosystem ever?
They don't even know when, if, who and when this was exploited, but maybe I didn't pay enough detail attention to the few paragraphs devoted to the real problem.
So shoudn't we assume all NPM packages published prior to 2nd of November are compromised?
