## Overview

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.

## Affected

- `zabbix >= 6.0.0, < 6.0.45`
- `zabbix >= 7.0.0, < 7.0.24`
- `zabbix >= 7.4.0, < 7.4.8`

## Remediation

Upgrade past the affected range:

- `zabbix 7.4.8`
