      <title>CVE-2026-23928 — Stored XSS vulnerability in the Item history/Plain text widget</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-23928</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Zabbix&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;</description>
