Quick assessment

Affected
Unknown Forminator Forms
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.

Forminator Forms WordPress 插件在 1.57.2.1 版本之前，未验证请求是否来自受信任的代理，就优先使用客户端提供的转发头信息而非实际连接地址。该插件利用该值来执行其每个访问者的投票限制，并记录每次提交条目的用户。因此，未经身份验证的访问者可以对任何投票无限投票，并选择每次提交时绑定的地址。

Vulnerability Title
Forminator Forms < 1.57.2.1 - Unauthenticated Poll Vote Limit Bypass via IP Spoofing
Source: CVE Program / CVE List V5
Vulnerability Description
The Forminator Forms WordPress plugin before 1.57.2.1 does not verify that a request came from a trusted proxy before preferring client-supplied forwarding headers over the connecting address, and it uses that value both to enforce its per-visitor voting limit and to record who submitted an entry. Unauthenticated visitors can therefore vote without limit on any poll and can choose the address stored against every submission they make.
