CVE-2026-114438

MEDIUM 4.2

Published 2026-10-21 · Last modified 2026-10-21

A flaw was found in the Update User Locale required action of the Keycloak identity and access management solution. When this action is ordered before the Configure OTP action in a realm, the system may fail to enforce mandatory multi-factor authentication enrollment during the login process. This issue allows an attacker with a valid password to access an account without setting up the required one-time password (OTP) credential.
