Overview
CVE-2026-78425 is a known-severity vulnerability. It was published on September 17, 2026.
Technical description
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.
