CVE-2026-78427

Admission Control Bypass via Hardcoded Sidecar Image Exemption

The NeuVector admission webhook silently excludes containers from policy evaluation when their image path matches one of three hardcoded service mesh sidecar images. Since the image path is entirely controlled by the workload author, any user capable of deploying workloads can evade admission deny rules simply by naming their image path after one of these sidecar images.

CVE-2026-78425

SAML Audience Confusion Allows Cross-SP Authentication

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.
