Formidable Forms WordPress 插件在 6.35 版本之前存在一个安全漏洞：该插件未限制哪些用户可以设置用于记录最近编辑表单条目的用户标识符，并且在决定是否从存储的条目值中去除 HTML 标签时，依赖于该标识符。这导致未认证的访客可以在管理端的条目视图中看到本应被移除的 HTML 标记被渲染出来，并能够将他们的提交归因于从未实际进行过操作的某个管理员。

Vulnerability Title
Formidable Forms 6.34 - Unauthenticated Stored Content Injection via 'updated_by' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The Formidable Forms WordPress plugin before 6.35 does not restrict who can set the identifier recording which user last edited a form entry, and relies on that identifier when deciding whether to strip HTML from stored entry values, allowing unauthenticated visitors to have markup rendered in the admin entry view that would otherwise be removed, and to attribute their submission to an administrator who never made it.
