Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.hazelcast

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-33265, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.hazelcast

Analyze the terminal output to locate any version of Hazelcast in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.2.4), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.hazelcast command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Hazelcast, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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).
