The CVE-2025-XXXX vulnerability is a reflected Cross-Site Scripting (XSS) flaw within Liferay Portal and Liferay DXP. It specifically exists in the handling of the `_com_liferay_expando_web_portlet_ExpandoPortlet_displayType` parameter. An authenticated attacker can craft a malicious URL containing JavaScript payloads within this parameter. When a victim, such as an administrator, is tricked into clicking the link, the server reflects the payload unsanitized back into the HTTP response. The victim’s browser then executes the injected script within the security context of the Liferay site, allowing the attacker to steal session cookies or perform actions on behalf of the user.
Platform: Liferay Portal/DXP
Version: 7.4.0-7.4.3.132, 2025.Q2.0-2025.Q2.8, 2025.Q1.0-2025.Q1.15, 2024.Q4.0-2024.Q4.7, 2024.Q3.1-2024.Q3.13, 2024.Q2.1-2024.Q2.13, 2024.Q1.1-2024.Q1.19
