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\n\n## Affected packages\n\n- `github.com/openbao/openbao >= 0.1.0, < 2.3.2`\n- `github.com/openbao/openbao < 0.0.0-20250806193153-183891f8d535`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `github.com/openbao/openbao 2.3.2`\n- `github.com/openbao/openbao 0.0.0-20250806193153-183891f8d535`","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
