JSON

jquery prior to 1.9.0 allows Cross-site Scripting attacks via the load
method. The load method fails to recognize and remove “<script>” HTML tags
that contain a whitespace character, i.e: “</script >”, which results in
the enclosed script logic to be executed.

Notes

Author	Note
mdeslaur	This is likely an intrusive, backwards-incompatible change that may break existing software. We will not be fixing this issue in stable Ubuntu releases.
