medium Tenable Cloud Security Plugin ID 438332

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - lxml_html_clean is a project for HTML cleaning functionalities copied from `lxml.html.clean`. Prior to
 version 0.4.4, the _has_sneaky_javascript() method strips backslashes before checking for dangerous CSS
 keywords. This causes CSS Unicode escape sequences to bypass the @import and expression() filters,
 allowing external CSS loading or XSS in older browsers. This issue has been patched in version 0.4.4.
