"The version of IBM WebSphere Application Server running on the remote host is affected by a remote code execution
vulnerability as referenced in the 7276560 advisory.

  - IBM WebSphere Application Server and IBM WebSphere Application Server Liberty, when using Intelligent
    Management with the WebSphere WebServer Plug-in component, are vulnerable to remote code execution and
    denial of service. This vulnerability can be exploited when an attacker impersonates backend servers and
    sends crafted responses to the plug-in. CWE: CWE-94: Improper Control of Generation of Code ('Code
    Injection') (CVE-2026-9072)

  - IBM WebSphere Application Server and IBM WebSphere Application Server Liberty are vulnerable to denial of
    service in the WebSphere WebServer Plug-in component when an attacker can pass crafted requests to the web
    server. CWE: CWE-476: NULL Pointer Dereference (CVE-2026-10852)

  - IBM WebSphere Application Server and IBM WebSphere Application Server Liberty are vulnerable to remote
    code execution and denial of service in the WebSphere Web Server Plug-in component. This vulnerability can

    in. CWE: CWE-94: Improper Control of Generation of Code ('Code Injection') (CVE-2026-8858)
