Quick assessment

Affected
wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder
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.

WordPress 的 Forminator Forms 插件在所有 1.55.0.2 及更早版本中存在“受限文件删除”漏洞。该漏洞的成因是：插件在处理草稿提交时，会接受来自 POST 请求中的任意上传字段元数据，且未进行适当的验证；随后，当后续草稿通过 参数引用该被投毒的草稿时，这些元数据会被用于删除文件。这使得未认证的攻击者能够删除 目录中的任意非 PHP 文件。

Vulnerability Title
Forminator Forms <= 1.55.0.2 - Unauthenticated Limited File Deletion via Draft Upload Metadata
Source: CVE Program / CVE List V5
Vulnerability Description
The Forminator Forms plugin for WordPress is vulnerable to Limited File Deletion in all versions up to, and including, 1.55.0.2. This is due to the plugin accepting arbitrary upload field metadata from POST requests in draft submissions without proper validation, which is then used to delete files when a subsequent draft references the poisoned draft via the previous_draft_id parameter. This makes it possible for unauthenticated attackers to delete arbitrary non-PHP files within the wp-content/uploads/ directory.
