Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

The Zabbix API host.get action can be exploited by authenticated users to extract a host's PSK key leading to potential loss of data integrity.
