WordPress 的 FV Flowplayer Video Player 插件在所有版本直至 7.5.54.7212 均存在有限任意文件上传漏洞，该漏洞位于 函数中。此漏洞源于 函数中文件类型验证不完整——尽管存在部分扩展名检查，但可被绕过，从而允许攻击者提供的远程文件内容在扩展名限制不足、无 MIME 类型检查且未使用 WordPress 上传辅助工具的情况下被写入。这使得具有订阅者及以上权限的经认证攻击者能够上传可能可执行的文件，进而可能导致远程代码执行。利用该漏洞需要启用插件的“个人资料中的个人资料视频”

Vulnerability Title
FV Flowplayer Video Player <= 7.5.54.7212 - Authenticated (Subscriber+) Arbitrary File Upload via 'video_url' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The FV Flowplayer Video Player plugin for WordPress is vulnerable to Limited Arbitrary File Upload in all versions up to, and including, 7.5.54.7212 via the check_mimetype function. This is due to incomplete file type validation in the check_mimetype function — while some extension checking is present, it can be bypassed, allowing attacker-supplied remote file content to be written with insufficient extension enforcement and no MIME check or WordPress upload helper. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. Exploitation requires the plugin's 'profile videos on bio' option to be enabled, as this causes the nonce to be emitted on the subscriber-accessible profile page; without this setting, authenticated users below Editor cannot obtain the required nonce.
