{"cve":"CVE-2025-55000","nvd":{"published":"2025-08-09T03:15:46.737","modified":"2026-06-17T09:41:05.530","status":"Analyzed","description":"OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including secrets, certificates, and keys. In versions 0.1.0 through 2.3.1, 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. To work around, ensure that all codes are first normalized before submitting to the OpenBao endpoint. TOTP code verification is a privileged action; only trusted systems should be verifying codes.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-156"],"references":["https://discuss.hashicorp.com/t/hcsec-2025-17-vault-totp-secrets-engine-code-reuse/76036","https://github.com/openbao/openbao/commit/183891f8d535d5b6eb3d79fda8200cade6de99e1","https://github.com/openbao/openbao/security/advisories/GHSA-f7c3-mhj2-9pvg"],"products":["openbao:openbao"],"source":"nvd","synced_at":"2026-10-19T22:06:45.861874017+00:00"},"epss":{"cve":"CVE-2025-55000","score":0.00236,"percentile":0.14711,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-f7c3-mhj2-9pvg","url":"https://osv.dev/vulnerability/GHSA-f7c3-mhj2-9pvg","summary":"OpenBao TOTP Secrets Engine Code Reuse","modified":"2026-07-27T09:11:26.771968198Z","packages":[{"ecosystem":"Go","name":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","ranges":[">=0.1.0 <2.3.2"],"fixed":["2.3.2"]},{"ecosystem":"Go","name":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","ranges":["<0.0.0-20250806193153-183891f8d535"],"fixed":["0.0.0-20250806193153-183891f8d535"]}]},{"id":"GO-2025-3853","url":"https://osv.dev/vulnerability/GO-2025-3853","summary":"OpenBao TOTP Secrets Engine Code Reuse in github.com/openbao/openbao","modified":"2026-07-27T09:11:26.771968198Z","packages":[{"ecosystem":"Go","name":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","ranges":["<0.0.0-20250806193153-183891f8d535",">=0.1.0"],"fixed":["0.0.0-20250806193153-183891f8d535"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
