New file type restrictions

In order to improve security and reliability, we are limiting the types of file uploads we support for both port-in documents and import TN documents. We are also adding validation to ensure that the content-type header, the file type extension, and the MIME-type are consistent with each other.

Effective March 2, 2023, Bandwidth will allow only the following types of files to be uploaded:

• CSV (“text/csv”)
• DOC (“application/msword”)
• DOCX (“application/vnd.openxmlformats-officedocument.wordprocessingml.document”)
• JPG/JPEG (“image/jpeg”)
• PDF (“application/pdf”)
• PNG (“image/png”)
• TXT (“text/plain”)
• TIFF (“image/tiff”)
• XLS (“application/vnd.ms-excel”)
• XLSX (“application/vnd.openxmlformats-officedocument.spreadsheetml.sheet”)
