Detailsinfo

A vulnerability, which was classified as very critical, was found in NeuVector up to 5.6.1. This affects an unknown part of the component SAML SSO. The manipulation with an unknown input leads to a assertion vulnerability. CWE is classifying the issue as CWE-617. The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-78425 since 08/24/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 09/17/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
