"The versions of Oracle Database Server installed on the remote host are affected by multiple vulnerabilities as
referenced in the August 2026 CSPU advisory.

  - Vulnerability in the Portable Clusterware component of Oracle Database Server. Supported versions that are
    affected are 19.3-19.32, 21.3-21.23 and 23.4.0-23.26.3. Easily exploitable vulnerability allows
    unauthenticated attacker with access to the physical communication segment attached to the hardware where
    the Portable Clusterware executes to compromise Portable Clusterware. While the vulnerability is in
    Portable Clusterware, attacks may significantly impact additional products (scope change). Successful
    attacks of this vulnerability can result in takeover of Portable Clusterware. (CVE-2026-71063,
    CVE-2026-71064)

  - Vulnerability in the Portable Clusterware component of Oracle Database Server. Supported versions that are
    affected are 19.3-19.32, 21.3-21.23 and 23.4.0-23.26.3. Easily exploitable vulnerability allows
    unauthenticated attacker with network access via HTTP to compromise Portable Clusterware. Successful
    attacks of this vulnerability can result in unauthorized creation, deletion or modification access to
    critical data or all Portable Clusterware accessible data and unauthorized ability to cause a hang or
    frequently repeatable crash (complete DOS) of Portable Clusterware. (CVE-2026-71102)

  - Vulnerability in the RDBMS component of Oracle Database Server. Supported versions that are affected are
    23.4.0-23.26.3. Easily exploitable vulnerability allows low privileged attacker having Authenticated User
    privilege with network access via Oracle Net to compromise RDBMS. Successful attacks of this vulnerability
    can result in unauthorized access to critical data or complete access to all RDBMS accessible data and
    unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of RDBMS.
    (CVE-2026-71062)
