Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Zammad 是一个基于 Web 的开源帮助台/客户支持系统。在版本 7.1.2 之前，Zammad 的管理界面中 AI 代理的配置对话框会渲染未经验证和清理的选项标签。当渲染所选选项列表时，选项标签会未经转义地以原始 HTML 形式输出。攻击者若能控制某个选项标签（例如，通过在关系属性中设置恶意的用户名或组织名，或提供精心构造的自定义属性选项值），即可注入任意 HTML 和 JavaScript 代码。该恶意载荷将在任何打开受影响对象属性配置视图的管理员或代理的浏览器中执行。此问题已在 7.1.2 版本中得到修复

Vulnerability Title
Zammad: Stored XSS via unescaped option labels in the object attribute options context UI
Source: CVE Program / CVE List V5
Vulnerability Description
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.
