Descripción
A flaw was found in Keycloak. This authentication vulnerability allows a remote attacker to replay `ExecuteActionsActionToken` tokens within Keycloak-s WebAuthn (Web Authentication) flow. By intercepting an execute-actions email link, an attacker can register their own authenticator to a victim-s account. This leads to unauthorized enrollment of a hardware-backed credential, enabling persistent account takeover.
