CVE-2026-28348: 1 source package rows (py3-lxml-html-clean); 4 state rows across 2 repos (3.23-community, edge-community); fixed 0, open 4.
lxml_html_clean is a project for HTML cleaning functionalities copied from `lxml.html.clean`. 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.
