Summary
Keycloak leaks configured LDAP bind credentials through the Keycloak admin console
Details

Impact

The LDAP testing endpoint allows to change the Connection URL independently of and without having to re-enter the currently configured LDAP bind credentials. An attacker with admin access (permission manage-realm) can change the LDAP host URL ("Connection URL") to a machine they control. The Keycloak server will connect to the attacker's host and try to authenticate with the configured credentials, thus leaking them to the attacker. As a consequence, an attacker who has compromised the admin console/compromised a user with sufficient privileges can leak domain credentials and can now attack the domain.
