Specifically this is an issue when:\n\n1. An operator in the root namespace has access to `identity/groups` endpoints.\n2. An operator does not have policy access.\n\nOtherwise, an operator with policy access could create or modify an existing policy to grant root-equivalent permissions through the `sudo` capability.\n\n### Patches\n\nPatched in version 2.4.4. \n\n### Workarounds\n\nUsers should audit the use of identity subsystem and deny operators access if it is not in use.","published":"2025-11-25T00:01:17.986Z","modified":"2026-10-28T02:30:42.650513497Z","cvss":null,"epss":{"score":0.00352,"percentile":0.28498,"asOf":"2026-08-20"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/openbao/openbao","fixedVersion":"2.4.4"}],"fix":{"url":"https://github.com/openbao/openbao/commit/16bb0ccd37a502930a289d434cbe4e7b4edd66e5","label":"openbao/openbao@16bb0cc"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/64xxx/CVE-2025-64761.json"},{"type":"ADVISORY","url":"https://github.com/openbao/openbao/security/advisories/GHSA-7ff4-jw48-3436"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-64761"},{"type":"FIX","url":"https://github.com/openbao/openbao/commit/16bb0ccd37a502930a289d434cbe4e7b4edd66e5"},{"type":"FIX","url":"https://github.com/openbao/openbao/pull/2143"},{"type":"WEB","url":"https://github.com/openbao/openbao/commit/747a1378c2756f86296ad9450f74f6faeecc2eb7"},{"type":"PACKAGE","url":"https://github.com/openbao/openbao"},{"type":"WEB","url":"https://github.com/openbao/openbao/releases/tag/v2.4.4"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:42.650513497Z"}}
