"The version of Oracle HTTP Server installed on the remote host is
affected by multiple vulnerabilities as referenced in the October 2026 CPU advisory.

  - Vulnerability in the Oracle HTTP Server product of Oracle Fusion Middleware (component: OSSL Module).
    Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows
    low privileged attacker with network access via HTTP to compromise Oracle HTTP Server. While the
    vulnerability is in Oracle HTTP Server, attacks may significantly impact additional products (scope change).
    Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access
    to critical data or all Oracle HTTP Server accessible data as well as unauthorized access to critical data or
    complete access to all Oracle HTTP Server accessible data. (CVE-2026-87347)

  - Vulnerability in the Oracle HTTP Server product of Oracle Fusion Middleware (component: Oracle Weblogic Server
    Proxy Plug-in for Oracle HTTP Server). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0.
    Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise
    Oracle HTTP Server. While the vulnerability is in Oracle HTTP Server, attacks may significantly impact
    additional products (scope change). Successful attacks of this vulnerability can result in unauthorized
    creation, deletion or modification access to critical data or all Oracle HTTP Server accessible data as well
    as unauthorized access to critical data or complete access to all Oracle HTTP Server accessible data.
    (CVE-2026-87346)

  - Vulnerability in the Oracle HTTP Server product of Oracle Fusion Middleware (component: OSSL Module). The
    supported version that is affected is 12.2.1.4.0. Easily exploitable vulnerability allows low privileged
    attacker with logon to the infrastructure where Oracle HTTP Server executes to compromise Oracle HTTP
    Server. Successful attacks of this vulnerability can result in takeover of Oracle HTTP Server.
