CVE-2025-43771Network attack vector

Stored script execution via unescaped notification values

Published Oct 8, 2025 · Updated Oct 8, 2025

Stored XSS in Liferay Portal 7.4.3.102 through 7.4.3.111 allows remote attackers to inject web script through notification data. FlagsUserNotificationHandler and AssetPublisherUserNotificationHandler render originalValue instead of escapedValue from notification JSON. Liferay DXP 2023.Q3.1 through 2023.Q3.10 and 2023.Q4.0 through 2023.Q4.5 is also affected; exploitation requires low-privileged access and a separate user to view the notification, executing the payload in that user's browser.
