NVD Description
Note: Versions mentioned in the description apply only to the upstream python3.14-lxml package and not the python3.14-lxml package as distributed by Centos.
lxml is a library for processing XML and HTML in the Python language. Prior to 6.1.1, link attributes in lxml.html.defs.link_attrs were missing xlink:href, which can be used for URL bypass attacks in embedded SVG/MathML/etc. content. This vulnerability was fixed in lxml 6.1.1 and lxml_html_clean 0.4.5.
