网易云音乐 Windows 客户端（cloudmusic.exe）版本 3.1.38 和 3.1.39.205426 存在远程代码执行漏洞。该漏洞位于渲染进程间通信（IPC）桥接函数 os.navigateExternal 中，该函数在未验证 URL 协议的情况下，直接将攻击者提供的 URL 传递给 ShellExecuteW 函数。 攻击者若能向渲染进程中注入恶意内容——例如，利用公开可用的 AES 密钥，在未经有效 TLS 验证的连接中伪造 /pc/upgrade/get API 响应——便可通过 img 标签

Vulnerability Title
NetEase Cloud Music RCE via os.navigateExternal IPC
Source: CVE Program / CVE List V5
Vulnerability Description
NetEase Cloud Music client for Windows (cloudmusic.exe) versions 3.1.38 and 3.1.39.205426 contains a remote code execution vulnerability in the renderer-process IPC bridge os.navigateExternal, which passes caller-supplied URLs to ShellExecuteW without validating the URL scheme. An attacker able to inject content into the renderer, such as by forging the /pc/upgrade/get API response using a publicly known AES key over an unvalidated TLS connection, can invoke os.navigateExternal with a file:// URL through an img onerror payload to execute arbitrary local binaries under the logged-in user's account.
