Quick assessment

Affected
Unknown weMail
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.

weMail WordPress 插件（2.1.6 及更早版本）未将全局第三方电子邮件服务 API 密钥限制为仅限管理员访问，导致该密钥暴露在一个默认情况下编辑器（Editor）角色用户也可访问的管理界面中。这使得攻击者能够获取可重复使用的凭据，该凭据无需 WordPress 会话即可用于冒充其他用户，并切断网站与电子邮件服务的连接。

Vulnerability Title
weMail <= 2.1.6 - Editor+ API Key Disclosure
Source: CVE Program / CVE List V5
Vulnerability Description
The weMail WordPress plugin through 2.1.6 does not restrict a site-wide third-party email-service API key to administrators, exposing it in an admin screen that users with the Editor role can reach by default, which allows them to obtain a reusable credential usable without a WordPress session to impersonate other users and sever the site's email-service connection.
