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.\nStarting from version 5.4.0, NeuVector supports TLS verification for following connection types:\n\n- Registry Connections\n- Auth Server Connections (SAML, LDAP and OIDC)\n- Webhook Connections\n\nBy default, TLS verification remains disabled, and its configuration is located under **Settings > Configuration in the NeuVector UI**.\n\nIn the patched version, the new NeuVector deployment enables TLS verification by default. \nFor rolling upgrades, NeuVector does not automatically change this setting to prevent disruptions.\n\n**Note:** When \"TLS verification\" is enabled, it affects all connections to:\n\n- Registry servers\n- Auth servers (SAML, LDAP and OIDC)\n- Webhook servers\n\n### Patches\n\nPatched versions include release v5.4.8 and above.\n\n### Workarounds\n\nTo manually enable TLS verification:\n\n1. Open the NeuVector UI.\n2. Navigate to **Settings > Configuration**.\n3. In the **TLS Self-Signed Certificate Configuration** section, select **Enable TLS verification**.\n4. (Optional) Upload or paste the **TLS self-signed certificate**.\n\n### References\n\nIf you have any questions or comments about this advisory:\n\n- Reach out to the [SUSE Rancher Security team](https://github.com/rancher/rancher/security/policy) for security related inquiries.\n- Open an issue in the [NeuVector](https://github.com/neuvector/neuvector/issues/new/choose) repository.\n- Verify with our [support matrix](https://www.suse.com/suse-neuvector/support-matrix/all-supported-versions/neuvector-v-all-versions/) and [product support lifecycle](https://www.suse.com/lifecycle/#suse-security).","state":0,"publishedAt":"2025-12-12T19:22:04+00:00","modifiedAt":"2026-09-10T03:50:31.5003404+00:00","affected":[{"ecosystem":"Go","name":"github.com/neuvector/neuvector","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"5.3.0"},{"kind":"fixed","version":"5.4.8"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/neuvector/neuvector/security/advisories/GHSA-4jj9-cgqc-x9h5","https://nvd.nist.gov/vuln/detail/CVE-2025-66001","https://github.com/neuvector/neuvector/commit/955904b5762f296d209bf395a5fcc7a40a53c424","https://bugzilla.suse.com/show_bug.cgi?id=CVE-2025-66001","https://github.com/neuvector/neuvector"],"sourceUrl":"https://github.com/advisories/GHSA-4jj9-cgqc-x9h5","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-4jj9-cgqc-x9h5","identifiers":["GHSA-4jj9-cgqc-x9h5","CVE-2025-66001","GO-2025-4235"]},"retained":false,"historicalAffected":[]},{"revision":"fa106f5336794f659499200a141df678","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2025-4235","aliases":["CVE-2025-66001","GHSA-4jj9-cgqc-x9h5"],"title":"NeuVector OpenID Connect is vulnerable to man-in-the-middle (MITM) in github.com/neuvector/neuvector","description":"NeuVector OpenID Connect is vulnerable to man-in-the-middle (MITM) in github.com/neuvector/neuvector","state":0,"publishedAt":"2025-12-15T20:37:41+00:00","modifiedAt":"2026-07-01T12:47:10.1011649+00:00","affected":[{"ecosystem":"Go","name":"github.com/neuvector/neuvector","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/neuvector/neuvector/security/advisories/GHSA-4jj9-cgqc-x9h5","https://github.com/neuvector/neuvector/commit/955904b5762f296d209bf395a5fcc7a40a53c424"],"sourceUrl":"https://osv.dev/vulnerability/GO-2025-4235","license":"OSV · upstream source license applies","key":"osv:GO-2025-4235","identifiers":["GO-2025-4235","CVE-2025-66001","GHSA-4jj9-cgqc-x9h5"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
