CVE ID :CVE-2026-14781<\/p>\n
Published : July 5, 2026, 7:16 a.m. | 31\u00a0minutes ago<\/p>\n
Description :A flaw exists in the org.keycloak.broker.oidc package where the OIDC broker incorrectly synchronizes the email_verified claim. 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).<\/p>\n
The userinfo endpoint must be enabled (default).<\/p>\n
The attacker must control or have compromised the upstream OIDC provider.<\/p>\n
Concrete Impact:
\nMark arbitrary email addresses as verified in the Keycloak database.<\/p>\n
Bypass email-based security controls or verification workflows.<\/p>\n
Potential account takeover if the application relies solely on the email_verified flag from the IdP to link accounts.<\/p>\n
Severity: 4.8 | MEDIUM<\/p>\n
