Description Vincent Danen 2014-06-09 17:46:17 UTC

It was reported [1],[2],[3] 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 [4] and 0.8.x [5] are available.
