Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

NeuVector supports OpenID Connect (OIDC) authentication, but TLS/SSL certificate verification for OIDC connections is not enforced by default. This allows a man-in-the-middle attacker to intercept the authentication flow, potentially capturing credentials or session tokens and impersonating the OIDC provider to gain unauthorized access to NeuVector.

MitigationEnable and enforce TLS certificate verification for all OpenID Connect connections in NeuVector's authentication configuration to ensure proper validation of the remote OIDC provider's identity.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify NeuVector is installed
    Run 'helm list' or check for neuvector pods via 'kubectl get pods -A | grep neuvector' to confirm NeuVector deployment exists
    Affected if NeuVector is not installed - the check does not apply
  2. Check if OIDC authentication is enabled
    Examine NeuVector authentication configuration files or CRD: 'kubectl get authentications -n neuvector' or check /etc/neuvector/ for OIDC-related configuration files
    Affected if OIDC is not enabled - the vulnerability does not apply
  3. Inspect TLS certificate verification settings for OIDC provider
    Review OIDC configuration for 'tls_verify', 'insecure_skip_verify', 'skip_tls_verify', or similar flags. Check CRD 'kubectl get authentications <name> -n neuvector -o yaml' and look for TLS-related parameters under the OIDC provider section
    Affected if TLS certificate verification is disabled, set to false, or missing for the OIDC connection - the environment is affected
  4. Compare installed NeuVector version to vendor advisories
    Run 'helm list' or 'kubectl get deployment -n neuvector' to find the installed version, then compare against CVE-2025-66001 affected version ranges if published by vendor
    Affected if Installed version falls within the affected range and OIDC with disabled TLS verification is in use

You are affected if OIDC authentication is enabled in NeuVector and TLS certificate verification for OIDC connections is not enforced (disabled or not configured), regardless of specific version.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
