{"id":"CVE-2025-66001","aliases":["GHSA-4jj9-cgqc-x9h5","GO-2025-4235"],"url":"https://o3.security/vulnerability/CVE-2025-66001","summary":"NeuVector OpenID Connect is vulnerable to man-in-the-middle (MITM)","details":"### Impact\n\nNeuVector 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.\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).","published":"2026-01-08T10:23:18.934Z","modified":"2026-08-12T03:51:17.632048281Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":{"score":0.00366,"percentile":0.3024,"asOf":"2026-09-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/neuvector/neuvector","fixedVersion":"5.4.8"}],"fix":{"url":"https://github.com/neuvector/neuvector/commit/955904b5762f296d209bf395a5fcc7a40a53c424","label":"neuvector/neuvector@955904b"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/66xxx/CVE-2025-66001.json"},{"type":"ADVISORY","url":"https://github.com/neuvector/neuvector/security/advisories/GHSA-4jj9-cgqc-x9h5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-66001"},{"type":"REPORT","url":"https://bugzilla.suse.com/show_bug.cgi?id=CVE-2025-66001"},{"type":"WEB","url":"https://github.com/neuvector/neuvector/commit/955904b5762f296d209bf395a5fcc7a40a53c424"},{"type":"PACKAGE","url":"https://github.com/neuvector/neuvector"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:17.632048281Z"}}
