Summary
python-lxml security update
Details

\

Security Fix(es):

lxmlhtmlclean.Cleaner does not strip javascript: URLs from namespaced URL attributes (xlink:href). The vulnerability exists because Cleaner filters URL schemes by walking links via rewritelinks(), which delegates to iterlinks(), which only yields attributes named in lxml.html.defs.linkattrs. That allow-list contains no prefixed names such as xlink:href. As a result, when Cleaner is configured with safeattrsonly=False, an xlink:href attribute carrying a javascript: URL survives sanitization untouched, and any browser that follows the SVG or MathML anchor specification will execute the JavaScript when the rendered link is clicked, leading to Cross-Site Scripting (XSS) attacks.(CVE-2026-49825)
