  • →Vulnerable functions span multiple CGI handlers in myMusic.cgi: cgi_audio_search, cgi_create_playlist, cgi_get_album_all_tracks, cgi_get_alltracks_editlist, cgi_get_artist_all_album, cgi_get_genre_all_tracks, cgi_get_tracks_list, cgi_set_airplay_content, cgi_write_playlist — all should be monitored. ↗
