CVE-2025-15691— WPFunnels < 3.13.0 - Unauthenticated User Registration via Opt-in Forms

Quick assessment

Affected
Unknown WPFunnels
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.

WPFunnels WordPress 插件在 3.13.0 之前的版本中，在从订阅表单提交创建账户时，未检查站点是否启用了用户注册功能，而是依赖于请求中提供的值，这使得未经身份验证的攻击者可以在禁用注册功能的情况下创建 WordPress 用户账户。 这是 CVE-2025-12353 的不完整修复：在 3.6.3 中增加的检查仅覆盖了三个注册路径中的一个。

Vulnerability Title
WPFunnels < 3.13.0 - Unauthenticated User Registration via Opt-in Forms
Source: CVE Program / CVE List V5
Vulnerability Description
The WPFunnels WordPress plugin before 3.13.0 does not check whether user registration is enabled on the site before creating accounts from opt-in form submissions, relying on a value supplied in the request instead, allowing unauthenticated attackers to create WordPress user accounts even when registration is disabled. This is an incomplete fix for CVE-2025-12353: the check added in 3.6.3 covers only one of the three registration paths.
