Summary
Authorised users of outside applications behind the same corporate identity provider (IdP), for example, a wiki, a ticketing system, an expenses tool, or anything they legitimately hold an account on can log into their system via SAML SSO. The IdP issues an assertion to them. If that assertion is presented to NeuVector, NeuVector accepts it because the only thing distinguishing "an assertion for NeuVector" from "an assertion for the wiki" is the element, and the `NotInAudience` warning that reports the mismatch is never read.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of neuvector/neuvector published their own advisory on GitHub. Reviewed sources take precedence over it.
