LibreOffice can link to audio and video files from a document, and on Linux it plays them with GStreamer. A linked media file could be an HLS playlist that made GStreamer read the local files and remote URLs it listed while the document loaded, and their contents could end up in the document. In fixed versions LibreOffice does not follow playlists that name further resources, and linked media is under link update control.
