MEDIUM 6.1EPSS 0.37%
Does this matter?
Lower severity and a low EPSS score (0.37%). Track it; it rarely justifies an emergency change on its own.
Description
The HTML Sanitizer should have sanitized the <code>href</code> attribute of SVG <code><use></code> tags; however it incorrectly did not sanitize <code>xlink:href</code> attributes. This vulnerability affects Firefox < 102.
