A low-privileged user can access information about profiles created in Proget MDM (Mobile Device Management), which contain details about allowed/prohibited functions. The profiles do not reveal any sensitive information (including their usage in connected devices). This issue has been fixed in 2.17.5 version of Konsola Proget (server part of the MDM suite).
A regular Zabbix user with no permission to the Monitoring -> Problems view is still able to call the problem.view.refresh action and therefore still retrieve a list of active problems.
