Official description

OpenCode Studio before 2.4.4 contains a missing authentication vulnerability that allows unauthenticated remote attackers to read arbitrary files within the temp and static/music directories by directly accessing the GET /api/tmp/:tmpFile and GET /api/music/:fileName endpoints. Attackers can retrieve intermediate audio, video artifacts, and subtitles belonging to other users' jobs, and additionally delete any video by ID through the unauthenticated DELETE /api/short-video/:videoId endpoint.
