The 8.0.26 and prior versions of MySQL Connectors installed on the remote host are affected by a vulnerability as referenced in the October 2020 CPU advisory. A Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/J). Supported versions that are affected are 8.0.26 and prior. Difficult to exploit vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Connectors. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all MySQL Connectors accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Connectors.

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
