Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
WordPress 的 GoSMTP Pro 插件在所有 1.2.3 及更早版本中，存在通过电子邮件日志正文中的评论内容引发的存储型跨站脚本（Stored XSS）漏洞。该漏洞源于输入数据未进行充分清洗以及输出未进行正确转义。这使得未经身份验证的攻击者能够在页面中注入任意 Web 脚本，当用户访问被注入的页面时，这些脚本将被执行。 该漏洞得以利用的原因是：WordPress 的评论 kses 过滤机制无法移除实体编码的标签定界符，导致攻击载荷能够以“安全文本”的形式通过内容审核；随后，核心邮件通知功能在生成邮件通知

Vulnerability Title
GoSMTP Pro <= 1.2.3 - Unauthenticated Stored Cross-Site Scripting via Comment Content via Email Log Body
Source: CVE Program / CVE List V5
Vulnerability Description
The GoSMTP Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content via Email Log Body in all versions up to, and including, 1.2.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit is made possible because WordPress comment kses does not strip entity-encoded tag delimiters, allowing the payload to pass moderation as safe text before being decoded into live HTML by core email notification functions and written verbatim into the plugin's email log database table.
