In versions 2.3.1 and below, OpenBao&#8217;s Login Multi-Factor Authentication (MFA) system allows enforcing MFA using Time-based One Time Password (TOTP). Due to normalization applied by the underlying TOTP library, codes were accepted which could contain whitespace; this whitespace could bypass internal rate limiting of the MFA method and allow reuse of existing MFA codes. This issue was fixed in version 2.3.2. To work around this, use of rate-limiting quotas can limit an attacker&#8217;s ability to exploit this: https:\/\/openbao.org\/api-docs\/system\/rate-limit-quotas\/.<br \/>\n<br \/>\n<strong>Severity:<\/strong> 5.7 | MEDIUM<br \/>\n<br \/>\nVisit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2025-55003 Published : Aug. 9, 2025, 3:15 a.m. | 16\u00a0minutes ago Description : OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including secrets, certificates, and keys.
