CVE-2026-63216

Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, unsanitized option labels are rendered in the configuration dialogs of AI Agents within Zammad's admin UI. When rendering the list of selected options, the option label is output as raw HTML without escaping. An attacker who can control an option label, for example by setting a malicious string as a user or organization name used in a relation attribute, or by supplying a crafted custom attribute option value, can inject arbitrary HTML and JavaScript. The payload executes in the browser of any admin or agent who opens the affected object attribute configuration view. This issue is fixed in version 7.1.2.
