Quick assessment

Affected
Unknown Ultimate Before After Image Slider & Gallery
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.

4.7.19 版本之前的 Ultimate Before After Image Slider & Gallery WordPress 插件未正确转义滑块的 before-label 值，导致其集成的客户端脚本在将该值重新注入 DOM 时缺乏必要的保护。这使得拥有 Author（作者）及以上角色的用户能够存储一段载荷（payload），该载荷将在任何查看该滑块的用户（包括管理员）的浏览器中执行。
