Quick assessment
Affected
JoomUnited WP File Download
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 WP File Download 插件在所有版本中均存在任意文件删除漏洞，原因是其 函数对文件路径的验证不足。这使得具有订阅者级别或更高权限的已认证攻击者可以删除服务器上的任意文件。如果删除了关键文件（例如 ），很容易导致远程代码执行。 该利用过程分为两个阶段： 1. 第一个请求发送至 任务，将路径遍历字符串持久化到文件元数据中； 2. 第二个请求发送至 任务，以触发 调用。 这两个端点均缺少权限检查（capability checks）和非CE（nonce）验证。

Vulnerability Title
WP File Download <= 6.3.4 - Authenticated (Subscriber+) Arbitrary File Deletion via 'remoteurl' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The WP File Download plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete function in all versions. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The two-stage exploit requires a first request to the file.save task to persist the path-traversal string into file metadata, followed by a second request to the file.delete task to trigger the unlink call — both endpoints lack capability checks and nonce enforcement.
