HIGHPre-NVD 7.67.6—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.6 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 73% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
