  "description": "lxml_html_clean is a project for HTML cleaning functionalities copied from \u0060lxml.html.clean\u0060. Prior to version 0.4.4, the _has_sneaky_javascript() method strips backslashes before checking for dangerous CSS keywords. This causes CSS Unicode escape sequences to bypass the @import and expression() filters, allowing external CSS loading or XSS in older browsers. This issue has been patched in version 0.4.4.",
