Official description
Kaleo Forms Admin in Liferay Portal 7.0.0 through 7.4.3.4, and Liferay DXP 7.4 GA, 7.3 GA through update 27, and older unsupported versions does not restrict the saving of request parameters in the portlet session, which allows remote attackers to consume system memory leading to denial-of-service (DoS) conditions via crafted HTTP request.
