Liferay Portal and Liferay DXP Reflected Cross-Site Scripting Vulnerability

Vulnerability

A reflected cross-site scripting vulnerability has been identified in Liferay Portal versions 7.4.0 through 7.4.3.132, as well as in Liferay DXP versions 2025.Q2.0 through 2025.Q2.9, 2025.Q1.0 through 2025.Q1.16, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.1 through 2024.Q2.13, and 2024.Q1.1 through 2024.Q1.19.
