How to fix?

Upgrade org.keycloak:keycloak-core to version 6.0.1 or higher.

Overview

org.keycloak:keycloak-core is an open source identity and access management solution.

Affected versions of this package are vulnerable to Information Exposure. Keycloak allows the end user token (access or id token JWT) to be used as the session cookie for browser sessions for OIDC. As a result an attacker with access to service provider backend could hijack user's browser session.
