CVE-2026-23928: Zabbix

Medium severity, CVSS 6.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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 products

  • Zabbix Zabbix: from 6.0.0, before 6.0.45 (fixed in 6.0.45); from 7.0.0, before 7.0.24 (fixed in 7.0.24); from 7.4.0, before 7.4.8 (fixed in 7.4.8)
