OpenBao TOTP Secrets Engine Code Reuse
### Impact OpenBao's TOTP secrets engine could accept valid codes multiple times rather than strictly-once. This was caused by unexpected normalization in the underlying TOTP library. ### Patches OpenBao v2.3.2 will patch this issue. In patching, codes which were not normalized (strictly N numeric digits) will now be rejected. This is a potentially breaking change. ### Workarounds TOTP 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. ### References This issue was disclosed to HashiCorp and is the OpenBao equivalent of the following tickets: - https://discuss.hashicorp.com/t/hcsec-2025-17-vault-totp-secrets-engine-code-reuse/76036 - https://nvd.nist.gov/vuln/detail/CVE-2025-6014
