CVE-2025-66001 (GCVE-0-2025-66001)

Vulnerability from cvelistv5 – Published: 2026-01-08 10:23 – Updated: 2026-01-08 14:56

Title

NeuVector OpenID Connect is vulnerable to man-in-the-middle (MITM)

Summary

NeuVector supports login authentication through OpenID Connect. However, the TLS verification (which verifies the remote server's authenticity and integrity) for OpenID Connect is not enforced by default. As a result this may expose the system to man-in-the-middle (MITM) attacks.

Severity ?

8.8 (High)

GHSA-4JJ9-CGQC-X9H5

Vulnerability from github – Published: 2025-12-12 19:22 – Updated: 2026-01-08 20:51

Summary

NeuVector OpenID Connect is vulnerable to man-in-the-middle (MITM)

Details

Impact

Registry Connections
Auth Server Connections (SAML, LDAP and OIDC)
Webhook Connections

By default, TLS verification remains disabled, and its configuration is located under Settings > Configuration in the NeuVector UI.

In the patched version, the new NeuVector deployment enables TLS verification by default. For rolling upgrades, NeuVector does not automatically change this setting to prevent disruptions.

Note: When "TLS verification" is enabled, it affects all connections to:

Registry servers
Auth servers (SAML, LDAP and OIDC)
Webhook servers

Patches

Patched versions include release v5.4.8 and above.

Workarounds

To manually enable TLS verification:

Open the NeuVector UI.
Navigate to Settings > Configuration.
In the TLS Self-Signed Certificate Configuration section, select Enable TLS verification.
(Optional) Upload or paste the TLS self-signed certificate.
