MIME type inference

Jan | Last updated: Jun 13, 2019 05:38PM UTC

When a JSON response is sent Burp cannot deduce the MIME type correctly if the content is: {"name " :"bla"} Instead of JSON Burp thinks the type is text. I tested several cases and it seems that the space at this specific location is the problem. Funny thing is, when tested with the following content, Burp has no problem to identify the MIME type correctly as JSON: [{"name " : "bla"}]

Thanks for letting us know about this. We will look at improving MIME type inference in future versions of Burp.
