Zabbix is an open-source software tool to monitor IT infrastructure such as networks, servers, virtual machines, and cloud services.

Zabbix version from 5.0.0 to 5.0.36
Zabbix version from 6.0.0 to 6.0.20

Successful exploitation could allow an attacker to execute arbitrary JavaScript code in the context of the interface or allow the attacker to access sensitive, browser-based information.
