      "value": "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."

      "value": "Music Player Daemon (MPD) antes de la versión 0.24.11 contiene una vulnerabilidad de falsificación de petición del lado del servidor en CurlInputPlugin donde CURLOPT_FOLLOWLOCATION se establece sin CURLOPT_REDIR_PROTOCOLS_STR, permitiendo a atacantes no autenticados eludir la restricción del esquema http/https al hacer que un servidor HTTP malicioso redirija a protocolos no HTTP como gopher, ftp, sftp, ldap, dict, rtmp o rtsp. Los atacantes pueden activar esta vulnerabilidad a través de comandos MPD que inician recuperaciones de URL, incluyendo add, readcomments, albumart, readpicture o load, para interactuar con servicios de red internos o restringidos en sistemas que ejecutan versiones de libcurl anteriores a la 7.85.0."
