How to fix?

Upgrade Debian:unstable zabbix to version 1:7.0.27+dfsg-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream zabbix package and not the zabbix package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

The Item history widget (in Zabbix 7.0+) or the Plain text widget (in Zabbix 6.0) can execute injected JavaScript when HTML display is enabled. This can allow an attacker to perform unauthorized actions depending on which user opens a dashboard containing these widgets. The malicious JavaScript would have to come from a monitored host controlled by the attacker. Note: the Item history widget is a replacement for the Plain text widget since Zabbix 7.0.
