• Maven com.hazelcast:hazelcast: >= 5.2.0, < 5.2.4 → fixed in 5.2.4 • Maven com.hazelcast:hazelcast: >= 5.1.0, < 5.1.7 → fixed in 5.1.7 • Maven com.hazelcast:hazelcast: < 5.0.5 → fixed in 5.0.5 • Maven com.hazelcast:hazelcast-enterprise: >= 5.2.0, < 5.2.4 → fixed in 5.2.4 • Maven com.hazelcast:hazelcast-enterprise: >= 5.1.0, < 5.1.7 → fixed in 5.1.7 • Maven com.hazelcast:hazelcast-enterprise: < 5.0.5 → fixed in 5.0.5

Impact In Hazelcast Platform, 5.0 through 5.0.4, 5.1 through 5.1.6, and 5.2 through 5.2.3, and Hazelcast IMDG (all versions up to 4.2.z), Executor Services don't check client permissions properly, allowing authenticated users to execute tasks on members without the required permissions granted. Patches Fix versions: 5.3.0, 5.2.4, 5.1.7, 5.0.5 Workarounds Users are only affected when they already use executor services (i.e., an instance exists as a distributed data structure).
