Description

bleach developer reports:

Attributes that have URI values weren't properly sanitized if the

values contained character entities. Using character entities, it

was possible to construct a URI value with a scheme that was not

allowed that would slide through unsanitized.

This security issue was introduced in Bleach 2.1. Anyone using

Bleach 2.1 is highly encouraged to upgrade.
