    Critical [CVE-2026-18963] Unauthenticated account takeover via reset-credentials flow bypass

    CVE-2026-18963Source published Source updated

    A flaw was found in the reset-credentials flow of the keycloak-services component, which is the core engine for identity and access management in Red Hat Build of Keycloak.

This can result in the attacker gaining full control over target user accounts by directly setting new credentials. The Red Hat Product Security team has assessed the severity of this vulnerability as Critical, given that it can be exploited by an unauthenticated remote attacker without any user interaction. Successful exploitation allows an attacker to gain full access to any user account by bypassing the email verification step in the password recovery process.…
