Description
Music Player Daemon (MPD) before version 0.24.11 contains a server-side request forgery vulnerability in CurlInputPlugin where CURLOPT_FOLLOWLOCATION is set without CURLOPT_REDIR_PROTOCOLS_STR, allowing unauthenticated attackers to bypass the http/https scheme restriction by causing a malicious HTTP server to redirect to non-HTTP protocols such as gopher, ftp, sftp, ldap, dict, rtmp, or rtsp. Attackers can trigger this vulnerability via MPD commands that initiate URL fetches, including add, readcomments, albumart, readpicture, or load, to interact with internal or restricted network services on systems running libcurl versions prior to 7.85.0.
