Version 2.1.3 (March 5th, 2018)
- 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.
Backwards incompatible changes
- Fixed some other edge cases for attribute URI value sanitizing and
improved testing of this code.
