Summary
The Flags module in Liferay Portal 7.3.1 and earlier, and Liferay DXP 7.0 before fix pack 96, 7.1 before fix pack 20, and 7.2 before fix pack 5, does not limit the rate at which content can be flagged as inappropriate, which allows remote authenticated users to spam the site administrator with emails
