NVD Description
Note: Versions mentioned in the description apply only to the upstream python39-chardet package and not the python39-chardet package as distributed by Rocky-Linux.
A XSS vulnerability was discovered in python-lxml's clean module. The module's parser didn't properly imitate browsers, which caused different behaviors between the sanitizer and the user's page. A remote attacker could exploit this flaw to run arbitrary HTML/JS code.
