  - IBM WebSphere Application Server and WebSphere Application Server Liberty are vulnerable to HTTP request
    smuggling. A remote attacker could smuggle a specially crafted request to the application server thereby
    allowing the attacker to bypass security controls, spoof identity, escalate privilege, and expose
    sensitive information. CWE: CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response
    Smuggling') (CVE-2026-8646)

  - IBM WebSphere Application Server and WebSphere Application Server Liberty are vulnerable to a denial of
    service, caused by sending a specially-crafted request. A remote attacker could exploit this vulnerability
    to cause the server to consume memory resources. CWE: CWE-400: Uncontrolled Resource Consumption
    (CVE-2026-9071, CVE-2026-9320)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
