Official description
AzuraCast before 0.24.0 contains a missing authorization vulnerability in the GET and POST /api/station/{station_id}/waveform/{media_id} routes, which lack Permissions middleware. Any authenticated user without station assignment can read another station's cached waveform JSON and overwrite it with attacker-supplied data, corrupting Visual Cue Editor data.
