What is CVE-2026-50233?

Lyrion Music Server 9.2.0 contains an arbitrary directory listing vulnerability in its readdirectory query, exposed through both the CLI service (TCP port 9090) and the HTTP JSON-RPC endpoint (/jsonrpc.js). The query accepts a folder parameter and lists its contents with no restriction to the configured media directories and no authentication in the default configuration, allowing a remote, unauthenticated attacker to enumerate arbitrary locations on the host filesystem.
