When an OIDC identity provider is configured with trustEmail=true and the userinfo endpoint is enabled, Keycloak retrieves the email address from the userinfo response but retrieves the email_verified status exclusively from the id_token.\nThe root cause is a lack of validation ensuring that the email_verified claim in the id_token actually refers to the email address returned by the userinfo endpoint. If these two sources return different email addresses, the id_token's email_verified=true claim is blindly applied to the userinfo email.\nExploitation Conditions:\nThe OIDC identity provider must have trustEmail set to true (non-default).\n\nThe userinfo endpoint must be enabled (default).\n\nThe attacker must control or have compromised the upstream OIDC provider.\n\n\nConcrete Impact:\nMark arbitrary email addresses as verified in the Keycloak database.\n\nBypass email-based security controls or verification workflows.\n\nPotential account takeover if the application relies solely on the email_verified flag from the IdP to link accounts."
