CVE-2022-34473

This vulnerability affects Firefox < 102.

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>&lt;use&gt;</code> tags; however it incorrectly did not sanitize <code>xlink:href</code> attributes. This vulnerability affects Firefox < 102.
