CSRF token disclosure via unchecked message origin
Published Mar 2, 2022 · Updated Jul 9, 2026
Origin validation error in Liferay Portal 7.4.3.4 through 7.4.3.8 and Liferay DXP 7.4 before update 5 allows remote attackers to read CSRF tokens. The Remote App bridge's receiveMessage handler accepts event messages without verifying that event.origin matches the configured Remote App, allowing its fetch path to expose the token to an attacker-controlled origin. The affected Remote App module must process a crafted message; the demonstrated consequence is token disclosure, not direct data modification or service interruption.
