Quick assessment

Mopidy Mopidy
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.

Mopidy 4.0.5 之前的版本存在路径遍历漏洞，该漏洞允许未经身份验证的客户端访问 file/media_dirs 目录之外的本地文件。其根本原因在于 FileLibraryProvider.lookup() 方法缺少必要的包含性检查（containment check）。攻击者可以通过 JSON-RPC 或 WebSocket 协议调用 core.library.lookup 或 core.tracklist.add，并传入 file:// URI，从而探测文件是否存在、读取标签元数据，以及播放沙箱外的文件

Vulnerability Title
Mopidy before 4.0.5 Path Traversal via File Backend library.lookup
Source: CVE Program / CVE List V5
Vulnerability Description
Mopidy before 4.0.5 contains a path traversal vulnerability that allows unauthenticated clients to access local files outside file/media_dirs because FileLibraryProvider.lookup() lacks a containment check. Attackers can call core.library.lookup or core.tracklist.add over JSON-RPC or WebSocket with file:// URIs to probe file existence, read tag metadata, and play out-of-sandbox files.
