Summary
Updated python-lxml packages fix a security vulnerability
Details

An XSS vulnerability was discovered in python-lxml’s clean module versions before 4.6.3. When disabling the safeattrsonly and forms arguments, the Cleaner class does not remove the formaction attribute allowing for JS to bypass the sanitizer. A remote attacker could exploit this flaw to run arbitrary JS code on users who interact with incorrectly sanitized HTML (CVE-2021-28957).
