Summary
AzuraCast before 0.24.0 contains a stored CSV formula injection vulnerability that allows station users with Media permission to persist formula-prefixed metadata via bulk media import. Attackers can import crafted titles, artists, or custom fields through /api/station/{station_id}/files/bulk so formulas evaluate when other users open exported CSVs in spreadsheets.
