Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

MISP 的 Overmind 主题中的统计视图存在一个存储型跨站脚本（XSS）漏洞。在事件通用卡片（event_general.ctp）和服务器/数据源预览卡片（preview_general.ctp）中，甜甜圈图例标签是通过将对象名称或分类键直接拼接进 innerHTML 字符串来构建的，且未进行 HTML 编码。由于 MISP 的对象名称（例如，属性名、事件名或服务器/数据源标识符）可由任何拥有足够权限创建或修改此类对象的已认证用户进行控制，攻击者可以构造一个包含恶意标记（例如 script 标签或事件处理属

Vulnerability Title
MISP Overmind: Stored Cross-Site Scripting via Unescaped Object Names in Statistics Legends
Source: CVE Program / CVE List V5
Vulnerability Description
MISP contains a stored cross-site scripting (XSS) vulnerability in the Overmind theme's statistics views. The event General card (event_general.ctp) and the server/feed preview card (preview_general.ctp) constructed donut chart legend labels by directly concatenating object name or category keys into an innerHTML string without HTML-encoding. Because MISP object names (e.g., attribute names, event names, or server/feed identifiers) are user-controllable by any authenticated user with sufficient permissions to create or modify such objects, an attacker could craft a name containing malicious markup (for example, a script tag or event-handler attribute). When any other user viewed the affected Overmind dashboard, the injected markup would be interpreted as live HTML/JavaScript in the victim's browser, executing in the context of the MISP application origin. This could allow session hijacking, data exfiltration, or arbitrary actions performed on behalf of the victim. The vulnerability requires the attacker to have low-level authenticated access to create or rename an object whose name is rendered in the legend, and the victim to view the Overmind event or server preview page. No special browser conditions or race conditions are required.
