NVD Description
Note: Versions mentioned in the description apply only to the upstream golang-tests package and not the golang-tests package as distributed by RHEL.
CVE-2026-27142 fixed a vulnerability in which URLs were not correctly escaped inside of a <meta> tag's <content> attribute. If the URL content were to insert ASCII whitespaces around the '=' rune inside of the <content> attribute, the escaper would fail to similarly escape it, leading to XSS.
