Description

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).
