This was caused by unexpected normalization in the underlying TOTP library.\n\n### Patches\n\nOpenBao v2.3.2 will patch this issue.\n\nIn patching, codes which were not normalized (strictly N numeric digits) will now be rejected. This is a potentially breaking change.\n\n### Workarounds\n\nTOTP code verification is a privileged action; only trusted systems should be verifying codes. Ensure that all codes are first normalized before submitting to the OpenBao endpoint.\n\n### References\n\nThis issue was disclosed to HashiCorp and is the OpenBao equivalent of the following tickets:\n\n- https://discuss.hashicorp.com/t/hcsec-2025-17-vault-totp-secrets-engine-code-reuse/76036\n- https://nvd.nist.gov/vuln/detail/CVE-2025-6014","affected":[{"package":{"name":"github.com/openbao/openbao","ecosystem":"Go","purl":"pkg:golang/github.com/openbao/openbao"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.1.0"},{"fixed":"2.3.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/08/GHSA-f7c3-mhj2-9pvg/GHSA-f7c3-mhj2-9pvg.json"}},{"package":{"name":"github.com/openbao/openbao","ecosystem":"Go","purl":"pkg:golang/github.com/openbao/openbao"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.0.0-20250806193153-183891f8d535"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/08/GHSA-f7c3-mhj2-9pvg/GHSA-f7c3-mhj2-9pvg.json"}}],"references":[{"type":"WEB","url":"https://github.com/openbao/openbao/security/advisories/GHSA-f7c3-mhj2-9pvg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-55000"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-6014"},{"type":"WEB","url":"https://github.com/openbao/openbao/commit/183891f8d535d5b6eb3d79fda8200cade6de99e1"},{"type":"WEB","url":"https://discuss.hashicorp.com/t/hcsec-2025-17-vault-totp-secrets-engine-code-reuse/76036"},{"type":"PACKAGE","url":"https://github.com/openbao/openbao"}],"database_specific":{"cwe_ids":["CWE-156"],"github_reviewed":true,"github_reviewed_at":"2025-08-08T14:42:49Z","nvd_published_at":"2025-08-09T03:15:46Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
