The supported version that is affected is 26.7.1. Difficult to exploit vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Connectors.  Successful attacks of this vulnerability can result in  unauthorized creation, deletion or modification access to critical data or all MySQL Connectors accessible data as well as  unauthorized access to critical data or complete access to all MySQL Connectors accessible data. CVSS 3.1 Base Score 6.8 (Confidentiality and Integrity impacts).
