scripting vulnerability as referenced in the 7242026 advisory:

  - IBM WebSphere Application Server Liberty 17.0.0.3 through 25.0.0.8 is vulnerable to stored cross-site
    scripting. This vulnerability allows a privileged user to embed arbitrary JavaScript code in the Web UI thus
    altering the intended functionality potentially leading to credentials disclosure within a trusted session.
