Related CVEs CVE-2021-43818

lxml is a library for processing XML and HTML in the Python language. Prior to version 4.6.5, the HTML Cleaner in lxml.html lets certain crafted script content pass through, as well as script content in SVG files embedded using data URIs.

For Debian 8 jessie, these problems have been fixed in version 3.4.0-1+deb8u5.

We recommend that you upgrade your lxml packages.
