## Overview

Hazelcast is a unified real-time data platform combining stream processing with a fast data store. Prior to 5.4.5, 5.5.10, and 5.6.1, missing authorization checks in the IMap Predicates API allow a malicious client with limited privileges to execute arbitrary code on a Hazelcast cluster member. This issue is fixed in versions 5.4.5, 5.5.10, 5.6.1, and 5.7.0.
