CVE-2026-97175

A flaw was found in the idp-auto-link authenticator of the keycloak-services component, which handles user identity federation.

Impact

A flaw was found in the idp-auto-link authenticator of the keycloak-services component, which handles user identity federation. The issue occurs when Keycloak automatically links an incoming identity from an external provider to an existing local account based on an email address without verifying if the provider has validated that email. This can allow an attacker to take over a victim's account by using a matching unverified email address at a brokered provider.

An attacker can exploit this over the network, with a regular user account, without any action by a user. If it succeeds: high risk of data being read, high risk of data or systems being changed, high risk of outages.
