Vault's Login MFA feature did not consistently enforce the lifetime of pending two-phase login requests. This may allow a user who previously completed the first authentication factor to complete MFA and obtain a Vault token after the pending request should have expired, including after the user's primary credential has been rotated. This vulnerability (CVE-2026-92738) is fixed in Vault Community Edition 2.2.2 and Vault Enterprise 2.2.2, 1.21.14, and 1.19.26.
