CVE-2018-19787: Improper Neutralization of Input During Web Page Generation in LXML
(updated )
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.
