It was reported ,, that Django's JSON serialization does not handle escaping of any characters to make them safe for injecting into HTML. This allows an attacker who can provide part of a JSON-serializable object to craft a string that can break out of a <script> tag and create its own, injecting a custom script.
To fix this, we escape '<', '>', and '&' characters in the resulting string, preventing a </script> from executing.
Patches for 0.7.x  and 0.8.x  are available.
