How to Fix CVE-2026-107725

To remediate this vulnerability, upgrade all affected Hazelcast dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.hazelcast:hazelcast fixed: 5.7.0
<dependency>
    <groupId>com.hazelcast</groupId>
    <artifactId>hazelcast</artifactId>
    <version>5.7.0</version>
</dependency>
com.hazelcast:hazelcast fixed: 5.7.0
<dependency>
    <groupId>com.hazelcast</groupId>
    <artifactId>hazelcast</artifactId>
    <version>5.7.0</version>
</dependency>
com.hazelcast:hazelcast fixed: 5.7.0
<dependency>
    <groupId>com.hazelcast</groupId>
    <artifactId>hazelcast</artifactId>
    <version>5.7.0</version>
</dependency>
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-2026-107725, 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 5.7.0), 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 Missing authorization checks in the [Predicates API](https://docs.hazelcast.com/hazelcast/5.7/query/predicate-overview) may allow a malicious client to execute arbitrary code on a Hazelcast member. ### Patches Enterprise customers should upgrade to a fixed version of Hazelcast Enterprise Edition: * 5.7.0 * 5.6.1 * 5.5.10 * 5.4.5 Customers with extended support contracts should contact Hazelcast Support for information on patches for older versions. Community Edition users should upgrade to version 5.7.0. ### Workarounds None - customers are advised to upgrade to a fixed version as soon as possible.
