Summary

Bleach is an HTML sanitizing library that escapes or strips markup and

attributes based on a white list.

Version 2.1.3 (March 5th, 2018) ------------------------------- **Security

fixes** * 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** None **Features** None **Bug fixes** * Fixed some other edge

cases for attribute URI value sanitizing and improved testing of this code.
