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

  - Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: Server: Compiling (OpenSSL)).
    Supported versions that are affected are MySQL Server: 8.4.0-8.4.12, 9.7.0-9.7.3, 26.7.0-26.7.1; MySQL Cluster:
    8.0.0-8.0.49, 8.4.0-8.4.12, 9.7.0-9.7.3 and 26.7.0-26.7.1. Easily exploitable vulnerability allows unauthenticated
    attacker with network access via multiple protocols to compromise MySQL Server, MySQL Cluster. Successful attacks of
    this vulnerability can result in takeover of MySQL Server, MySQL Cluster. (CVE-2025-15467)

  - Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: Server: Group Replication GCS).
    Supported versions that are affected are MySQL Server: 8.4.0-8.4.12, 9.7.0-9.7.3, 26.7.0-26.7.1; MySQL Cluster:
    8.0.0-8.0.49, 8.4.0-8.4.12, 9.7.0-9.7.3 and 26.7.0-26.7.1. Easily exploitable vulnerability allows unauthenticated
    attacker with access to the physical communication segment attached to the hardware where the MySQL Server, MySQL
    Cluster executes to compromise MySQL Server, MySQL Cluster. Successful attacks of this vulnerability can result in
    takeover of MySQL Server, MySQL Cluster. (CVE-2026-101781)

  - Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: Server: JSON). Supported versions
    that are affected are MySQL Server: 8.4.0-8.4.12, 9.7.0-9.7.3, 26.7.0-26.7.1; MySQL Cluster: 8.0.0-8.0.49, 8.4.0-8.4.12,
    9.7.0-9.7.3 and 26.7.0-26.7.1. Easily exploitable vulnerability allows low privileged attacker with network access via
    multiple protocols to compromise MySQL Server, MySQL Cluster. Successful attacks of this vulnerability can result in
    unauthorized creation, deletion or modification access to critical data or all MySQL Server, MySQL Cluster accessible
    data as well as unauthorized read access to a subset of MySQL Server, MySQL Cluster accessible data and unauthorized
    ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server, MySQL Cluster. (CVE-2026-101785)
