Technical details
A stored CSV formula injection vulnerability (CWE-1236) in the bulk media import endpoint allows authenticated users with Media permission to persist formula-prefixed content (starting with =, +, -, @) in media titles, artist names, album names, and custom fields. The payload is stored without sanitization and evaluated when other authorized users export and open the CSV in formula-capable spreadsheet applications, potentially leading to data manipulation or information disclosure depending on spreadsheet functionality and user interaction.
