CVE-2026-23928 is fixed in zabbix on 1 platform by DEBIAN-CVE-2026-23928 (version 1:7.0.27+dfsg-1), released May 6, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
