CVE-2026-78425: CWE-287 Improper Authentication in go github.com/neuvector/neuvector
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.
AI Analysis
Technical Summary
This vulnerability arises because NeuVector accepts SAML assertions issued by a corporate IdP without properly validating that the assertion is intended for NeuVector. The only difference between an assertion for NeuVector and one for another application (e.g., wiki, ticketing system) is the audience element. NeuVector fails to read the NotInAudience warning that indicates a mismatch, resulting in improper authentication (CWE-287). This allows users authorized on other applications within the same IdP to gain unauthorized access to NeuVector.
Potential Impact
An attacker who is an authorized user of any other application behind the same corporate IdP can use their valid SAML assertion to authenticate to NeuVector without proper authorization. This can lead to unauthorized access to NeuVector resources, potentially compromising the security of the system. The CVSS 4.0 score of 7.6 (high) reflects the network attack vector, low attack complexity, and significant impact on confidentiality and integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, organizations should consider restricting SAML assertions to trusted audiences or implementing additional validation controls on the SAML assertions received by NeuVector.
