"The version of Esri Portal for ArcGIS installed on the remote host is 11.1, 11.3, or 11.5 and is missing the Security
2026 Update 3 Patch. It is, therefore, affected by multiple vulnerabilities:

  - A reflected cross site scripting vulnerability exists in Esri Portal for ArcGIS which may allow a remote,
    unauthenticated attacker to create a crafted link which when clicked could potentially execute arbitrary
    JavaScript code in the victim's browser. (CVE-2026-69234)

  - A stored cross site scripting issue exists in Esri Portal for ArcGIS that may allow a remote, privileged attacker
    to inject malicious code that could potentially execute arbitrary script code in a victim's browser.
    (CVE-2026-69235)

  - A stored cross site scripting issue exists in Esri Portal for ArcGIS that may allow a remote, administratively
    privileged attacker to inject malicious code that could potentially execute arbitrary script code in a victim's
    browser. (CVE-2026-69233)

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