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.

An issue was discovered in lxml before 4.2.5. lxml/html/clean.py in the lxml.html.clean module does not remove javascript: URLs that use escaping, allowing a remote attacker to conduct XSS attacks, as demonstrated by "j a v a s c r i p t:" in Internet Explorer. This is a similar issue to CVE-2014-3146.
