CVE-2026-28350 is fixed in 3 products on 1 platform, first by DEBIAN-CVE-2026-28350, released March 5, 2026. It is not reported as exploited. Patch Radar priority: Routine.
lxml_html_clean is a project for HTML cleaning functionalities copied from `lxml.html.clean`. Prior to version 0.4.4, the <base> tag passes through the default Cleaner configuration. While page_structure=True removes html, head, and title tags, there is no specific handling for <base>, allowing an attacker to inject it and hijack relative links on the page. This issue has been patched in version 0.4.4.
