CVE-2026-28350
MEDIUM6.1EPSS 0.02%lxml-html-clean has <base> tag injection through default Cleaner configuration
發布日:2026/3/2修改日:2026/4/28
描述
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.
