CVE-2025-62239Network attack vector

Stored XSS via unsanitized workflow definition XML

Published Oct 10, 2025 · Updated Oct 10, 2025

Stored XSS in affected Liferay Portal and DXP releases allows remote authenticated users to inject script through workflow definitions. SourceBuilder passes edited or imported workflow XML directly to the editor, while XMLUtil accepts definitions containing script-relevant attributes without rejecting them. High-privilege workflow access and a victim's interaction with the crafted content are required, enabling script execution in that user's browser.
