CVE-2025-66723Public exploitNetwork attack vector

Unauthenticated file disclosure via unrestricted download paths

Published Dec 30, 2025 · Updated Dec 30, 2025

Arbitrary file read in inMusic Brands Engine DJ before 4.3.4 allows remote attackers to read local and network files over HTTP. The Remote Library server listens on TCP port 50020 and accepts absolute filesystem paths at its download endpoint without authentication or a path allowlist. Network reachability is sufficient to retrieve files readable by the Engine DJ process, while normal browser-origin attacks are blocked by cross-origin restrictions.
