"The 26.7.0 versions of MySQL Connector/ODBC installed on the remote host are affected by multiple vulnerabilities as
referenced in the August 2026 CSPU advisory.

  - Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/ODBC). The supported version
    that is affected is 26.7.0. Easily exploitable vulnerability allows unauthenticated attacker with logon to the
    infrastructure where MySQL Connectors executes to compromise MySQL Connectors. Successful attacks of this
    vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of
    MySQL Connectors and unauthorized read access to a subset of MySQL Connectors accessible data. (CVE-2026-71084)

  - Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/ODBC). The supported version
    that is affected is 26.7.0. Easily exploitable vulnerability allows low privileged attacker with network access
    via multiple protocols to compromise MySQL Connectors. Successful attacks of this vulnerability can result in
    unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Connectors.
    (CVE-2026-71079)

  - Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/ODBC). The supported version
    that is affected is 26.7.0. Easily exploitable 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 hang or frequently repeatable crash (complete DOS) of MySQL Connectors.
