Contest Gallery 插件在 33.0.1 版本之前，未对其前端注册电子邮件验证步骤尝试次数进行限制。该验证步骤依赖一个较短的数字 PIN 码，这使得未认证的攻击者可以暴力破解该 PIN 码，从而创建并激活一个绑定到其不拥有邮箱地址的 WordPress 账户，进而获得已认证的会话权限。

Contest Gallery < 33.0.1 - Unauthenticated Email Verification Bypass via Brute-Forceable Registration PIN

Vulnerability Description
The Contest Gallery WordPress plugin before 33.0.1 does not limit the number of attempts against its front-end registration email-verification step, which relies on a short numeric PIN, allowing unauthenticated attackers to brute-force the PIN and create and activate a WordPress account bound to an email address they do not own, gaining an authenticated session.
