Quick assessment

Affected
Unknown WP Mail Logging
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.

WP Mail Logging WordPress 插件在 1.17.0 版本之前，未对其管理员日志界面中显示的已记录电子邮件的 HTML 和 CSS 进行充分限制。这使得未经身份验证的用户能够通过公共联系表单等途径注入带样式的恶意内容和链接。这些内容可能诱骗查看日志的管理员点击链接，从而将浏览器重定向到由攻击者控制的页面。
