# HashiCorp Vault: expired login MFA requests can still issue tokens

Link for people: https://infrastack.ai/live/CVE-2026-92738 (this .md is for agents)

Vault's Login MFA feature did not consistently enforce the lifetime of pending two-phase login requests. A user who passed the first factor can finish MFA after the request should have expired and get a Vault token, even after the primary credential was rotated.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Vault affected range not listed fixed no fixed version listed

## How to check

- Check the running Vault version with `vault version` and compare it to the fixed versions.
- Look for Login MFA enabled in the Vault server configuration.

## Fix

- Vault Community Edition: `2.2.2`
- Vault Enterprise: `2.2.2`, `1.21.14`, `1.19.26`

## Documents

- [mentions] HashiCorp security: HCSEC-2026-59 - Expired Vault login MFA requests may remain redeemable https://discuss.hashicorp.com/t/hcsec-2026-59-expired-vault-login-mfa-requests-may-remain-redeemable/78257

## From the sources

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.
