In versions 0.1.0 through 2.3.1, attackers could bypass the automatic user lockout mechanisms in the OpenBao Userpass or LDAP auth systems. This was caused by different aliasing between pre-flight and full login request user entity alias attributions. This is fixed in version 2.3.2. To work around this issue, existing users may apply rate-limiting quotas on the authentication endpoints:, see https://openbao.org/api-docs/system/rate-limit-quotas/.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-307"],"references":["https://discuss.hashicorp.com/t/hcsec-2025-16-vault-userpass-and-ldap-user-lockout-bypass/76035","https://github.com/openbao/openbao/commit/c52795c1ef746c7f2c510f9225aa8ccbbd44f9fc","https://github.com/openbao/openbao/security/advisories/GHSA-j3xv-7fxp-gfhx"],"products":["openbao:openbao"],"source":"nvd","synced_at":"2026-10-19T22:06:45.861874017+00:00"},"epss":{"cve":"CVE-2025-54998","score":0.00233,"percentile":0.14267,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-j3xv-7fxp-gfhx","url":"https://osv.dev/vulnerability/GHSA-j3xv-7fxp-gfhx","summary":"OpenBao Userpass and LDAP User Lockout Bypass","modified":"2026-07-27T09:11:27.129915657Z","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":["<0.0.0-20250807212521-c52795c1ef74"],"fixed":["0.0.0-20250807212521-c52795c1ef74"]}]},{"id":"GO-2025-3855","url":"https://osv.dev/vulnerability/GO-2025-3855","summary":"OpenBao Userpass and LDAP User Lockout Bypass in github.com/openbao/openbao","modified":"2026-07-27T09:11:27.129915657Z","packages":[{"ecosystem":"Go","name":"github.com/openbao/openbao","purl":"pkg:golang/github.com/openbao/openbao","ranges":["<0.0.0-20250807212521-c52795c1ef74",">=0.1.0"],"fixed":["0.0.0-20250807212521-c52795c1ef74"]}]}],"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).
