CVE-2020-27783
A XSS vulnerability was discovered in python-lxml's clean module.
MEDIUM 6.1EPSS 3.98%
Does this matter?
Lower severity and a low EPSS score (3.98%). Track it; it rarely justifies an emergency change on its own.
Description
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.
