</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=com.hazelcastHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2023-33264, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=com.hazelcastAnalyze 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 5.0.5), 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-522: Insufficiently Protected Credentials, where the product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval. 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.
