JSON Security Fix

Flask previously decoded incoming JSON bytes using the content type of the request. Although JSON should only be encoded as UTF-8, Flask was more lenient. However, Python includes non-text related encodings that could result in unexpected memory use by a request.

Flask will now detect the encoding of incoming JSON data as one of the supported UTF encodings, and will not allow arbitrary encodings from the request.

Install from PyPI with pip:

pip install -U Flask
