"The version of IBM WebSphere Application Server running on the remote host is affected by multiple vulnerabilities as
referenced in the 7283567 advisory.

  - An incomplete fix for CVE-2026-50645 means that it is still possible to perform a denial of service attack
    on Apache CXF by sending a message with many attachment headers. Users are recommended to upgrade to
    versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue. (CVE-2026-64958)

  - Apache CXF allows to set a limit on the number of form parameters in a JAX-RS message via the
    maxFormParameterCount configuration option. However, no default limit is set which may lead to denial of
    service attacks when processing requests with very large numbers of form parameters. Users are recommended
    to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue by using a default limit of 500
    parameters. (CVE-2026-57819)

  - Apache CXF allows to control the maximum attachment size via the attachment-max-size. Prior to Apache
    CXF 4.2.3 and 4.1.8 and 3.6.12, there was no default placed on this size, meaning that a denial of service
    attack is possible if the user doesn't explicitly set the limit. Users should update to Apache CXF 4.2.3
    or 4.1.8 or 3.6.12 which fixes this problem by imposing a default attachment size limit of 50mb.
