CVE-2026-50233Public exploitNetwork attack vector

Unauthenticated directory enumeration via unrestricted folder query

Published Jun 5, 2026 · Updated Jun 5, 2026

Directory listing in Lyrion Music Server 9.2.0 allows remote attackers to enumerate host directories through unauthenticated network queries. The readdirectory query accepts an arbitrary folder value and returns its contents through TCP port 9090 or /jsonrpc.js without limiting access to configured media directories. Default configurations require no authentication, allowing remote attackers with network access to discover directory names and filesystem layout, but not reported file contents.
