漏洞描述翻译： Cyberdrop-DL 是一个用于多个文件托管平台的大容量异步下载器。在 8.5.0 到 9.14.0 版本中，Pixeldrain 爬虫使用子串主机匹配，而非要求输入主机名必须是 中的精确成员，随后在发起 API 请求时直接复用了该输入主机名。 当配置了 Pixeldrain API 密钥时，如果处理来自攻击者控制的仿冒（lookalike）主机的特制 URL， 会向该主机发送带有 请求头的请求。该 URL 可能通过第三方站点引入，从而触发对其他站点的下载操作，最终导致攻击者获取用户的 Pixe

Vulnerability Title
Cyberdrop-DL: Pixeldrain API key shared with unverified thirdparty sites
Source: CVE Program / CVE List V5
Vulnerability Description
Cyberdrop-DL is a bulk asynchronous downloader for multiple file hosts. From 8.5.0 until 9.14.0, the Pixeldrain crawler uses substring host matching instead of requiring the input host to be an exact member of SUPPORTED_DOMAINS, and then reuses that input host for API requests. When a Pixeldrain API key is configured, processing a crafted URL from an attacker-controlled lookalike host causes cyberdrop_dl/crawlers/pixeldrain.py to send the Authorization header to that host. The URL may be introduced through a third-party site that can cause downloads for other sites, and the attacker receives the user's Pixeldrain API key. This issue is fixed in version 9.14.0.
