CVE-2022-28982Network attack vector

Script execution via unescaped tag label

Published Sep 21, 2022 · Updated Jul 9, 2026

Cross-site scripting in Liferay Portal 7.3.3 through 7.4.2 allows remote attackers to execute scripts or HTML via crafted tag names. The asset-tags-selector page rendered selected tag labels directly in a Clay label without HtmlUtil escaping, allowing injected markup to reach the browser. Remote attackers require a victim to load the crafted request; the documented impact is script or HTML execution with confidentiality and integrity effects but no availability impact.
