Quick assessment

Affected
Unknown Eventin
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 Eventin WordPress 插件 4.1.24 版本之前，当添加演讲者时，插件未验证用户是否具备创建账户的权限。这使得拥有“贡献者”（Contributor）及以上权限的用户能够创建新的 WordPress 用户账户，而这些新账户所拥有的权限超过了创建者自身的权限范围，包括发布内容和上传文件的权限。此外，攻击者可以通过提供一个自己控制的电子邮箱地址，获取该新建账户的有效登录凭证。
