Quick assessment

Affected
Unknown LiteSpeed Cache
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 7.9.2 版本之前的 LiteSpeed Cache WordPress 插件中，其 HTML 优化功能未将范围限制在样式表内容内，导致该功能可能删除渲染页面中用于闭合属性的标记。结合未转义的评论作者输出，这使得已发布评论的非认证用户能够注入事件处理器属性，从而在任意访客（包括已登录的管理员）访问前端页面且优化功能启用时，在其浏览器中执行 JavaScript 代码。

Vulnerability Title
LiteSpeed Cache < 7.9.2 - Unauthenticated Stored XSS via Font Display Optimization
Source: CVE Program / CVE List V5
Vulnerability Description
The LiteSpeed Cache WordPress plugin before 7.9.2 does not limit one of its HTML optimization routines to stylesheet content, so it can delete the markup that closes an attribute in the rendered page, and combined with unescaped comment author output this allows unauthenticated users whose comments are published to inject event-handler attributes that run JavaScript in the browser of any visitor, including a logged-in administrator, viewing front-end pages while the optimization is enabled.
