NVD Description
Note: Versions mentioned in the description apply only to the upstream python3-sqlalchemy package and not the python3-sqlalchemy package as distributed by Rocky-Linux.
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. Users that employ the HTML cleaner in a security relevant context should upgrade to lxml 4.6.5 to receive a patch. There are no known workarounds available.
