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 3.15.2 之前版本的 Ninja Forms WordPress 插件并未将其 REST API 权限严格限制为仅管理员可用，而是将该插件特有的权限（capability）视为等同于完整的站点管理权限。因此，任何被授予该权限的用户都可以： 查看 Ninja Forms 的设置信息以及已存储的表单提交数据； 覆盖 Ninja Forms 的配置； 创建或修改任意文章和页面。 该权限不属于 WordPress 默认角色，且 3.15.2 之前的 Ninja Forms 插件本身也从未自动授予此权限，因此必须由管

Vulnerability Title
Ninja Forms 3.14.0 - 3.15.1 - Authenticated Arbitrary Post Modification and Sensitive Information Disclosure via Abilities REST API
Source: CVE Program / CVE List V5
Vulnerability Description
The Ninja Forms WordPress plugin before 3.15.2 does not restrict its REST abilities to administrators, accepting a Ninja Forms WordPress plugin before 3.15.2-specific capability as equivalent to full site administration, which allows any user granted that capability to read Ninja Forms WordPress plugin before 3.15.2 settings and stored form submissions, overwrite the Ninja Forms WordPress plugin before 3.15.2's configuration, and create or modify arbitrary posts and pages. The capability belongs to no default WordPress role and the Ninja Forms WordPress plugin before 3.15.2 never grants it, so an administrator must have assigned it, typically when delegating access to the form builder.
