CVE-2021-39211

GLPI is a free Asset and IT management software package. Starting in version 9.2 and prior to version 9.5.6, the telemetry endpoint discloses GLPI and server information. This issue is fixed in version 9.5.6. As a workaround, remove the file `ajax/telemetry.php`, which is not needed for usual functions of GLPI.
