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

  - Vulnerability in the RDBMS 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 low privileged attacker
    having Execute on DBMS_REDEFINITION privilege with network access via Oracle Net to compromise RDBMS.
    Successful attacks of this vulnerability can result in takeover of RDBMS. (CVE-2026-83271)
