CVE-2026-23926 Details
Description
An authenticated (non-super) administrator can create a maintenance period with a JavaScript payload that is executed by any user that opens tooltip for that maintenance period in the Host navigator widget. This can allow the attacker to perform unauthorized actions depending on which user opens the tooltip.
A stored cross-site scripting vulnerability has been identified in Zabbix versions 7.0.0 through 7.0.23 and 7.4.0 through 7.4.7. This vulnerability allows an authenticated (non-super) administrator to create a maintenance period containing a JavaScript payload. When any user opens the tooltip for that maintenance period in the Host navigator widget, the payload is executed. This could enable the attacker to perform unauthorized actions, depending on the user who opens the tooltip.
Users can update to Zabbix version 7.0.24 or 7.4.8, depending on their current version. Alternatively, the Host navigator widget can be disabled via the Administration -> General -> Modules menu.
