Description Josh Bressers 2010-09-03 16:08:46 UTC 
Security researchers David Lin-Shung Huang and Collin Jackson of Carnegie
Mellon University CyLab reported that the type attribute of an <object> tag
can override the charset of a framed HTML document, even when the document
is included across origins. A page could be constructed containing such an
<object> tag which sets the charset of the framed document to UTF-7. This
could potentially allow an attacker to inject UTF-7 encoded JavaScript into
a site, bypassing the site's XSS filters, and then executing the code using
the above technique.
