Technical details

The GET and POST /api/station/{station_id}/waveform/{media_id} routes in backend/config/routes/api_station.php lack the Permissions middleware present on sibling media routes, and neither controller action performs inline ACL checks. An authenticated user can exploit this to read arbitrary stations' waveform JSON and overwrite it with attacker-supplied content, with minor resource-consumption side effects on cache misses.
