Unauthenticated form submission disclosure via unchecked CSV export

Published Jun 27, 2026 · Updated Jun 27, 2026

Missing authorization in Basix NEX-Forms 9.2.2 and earlier allows remote attackers to download saved form submissions through CSV exports. The CSVExport class accepts a sequential report identifier and generates a complete export without verifying that the requester is authorized to access that report. No authentication is required, and exposed records include contact, payment, and uploaded-file-path data from any saved report whose identifier is enumerated.
