From the 10.0.0 release notes:

Previously, string attachments were included as plain text in the JSON formatter output, where other attachments were Base64 encoded. This meant for consumers, it was ambiguous whether any attachment was Base64 encoded or not. Now, all attachments are Base64 encoded regardless of how they were initially attached.

The code that produces your HTML report from the JSON output will need to Base64 decode the attachment body.
