Quick assessment

Affected
Unknown Firelight Lightbox
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 2.3.23 版本之前，Firelight Lightbox WordPress 插件在其经典（Classic）灯箱功能中打开链接时，未对链接的 URL 进行转义处理，便将其作为 HTML 插入页面。这可能导致角色低至“投稿者（Contributor）”的用户，通过构造恶意链接，对点击该链接的用户发起存储型跨站脚本（Stored XSS）攻击。
