  - A user with Editor permissions can place a malicious script in the attribution field of a Geomap panel's
    XYZ tile layer via a template variable. The script then executes in the browser of any user who views
    the affected dashboard (stored cross-site scripting). (CVE-2026-9029)

  - A user with Editor permissions can craft a dashboard whose table (TableNG) panel contains a malicious
    field name that executes as a script in the browser of any user who views the dashboard (stored
    cross-site scripting). (CVE-2026-8595)

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