"The versions of MySQL Connectors installed on the remote host are affected by multiple vulnerabilities as referenced in
the October 2026 CPU advisory.

  - Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/ODBC). 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. (CVE-2026-101806)

  - Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/ODBC). The supported version that
    is affected is 26.7.1. Difficult to exploit vulnerability allows unauthenticated attacker with logon to the
    infrastructure where MySQL Connectors executes to compromise MySQL Connectors. Successful attacks require human
    interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized
    ability to cause a partial denial of service (partial DOS) of MySQL Connectors. (CVE-2026-101804)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
