How to fix?

There is no fixed version for Centos:7 python-lxml.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-lxml package and not the python-lxml package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

A XSS vulnerability was discovered in python-lxml's clean module. The module's parser didn't properly imitate browsers, which caused different behaviors between the sanitizer and the user's page. A remote attacker could exploit this flaw to run arbitrary HTML/JS code.
