How to fix?

Upgrade com.hazelcast:hazelcast to version 5.7.0 or higher.

Overview

com.hazelcast:hazelcast is a clustering and highly scalable data distribution platform.

Affected versions of this package are vulnerable to Missing Authorization in the MapPermission component, through the IMap Predicates API, permission checks in hazelcast/src/main/java/com/hazelcast/security/permission/MapPermission.java. An attacker can execute unauthorized map predicate, aggregate, or projection operations by sending requests that use those query paths without the corresponding permission bits being recognized. Because MapPermission did not include AGGREGATE and PROJECTION in its action mask or parse those action names, the security layer treated those operations as permitted under weaker map access rules. That lets a malicious client reach map query functionality it should not have, with the potential for arbitrary code execution on a Hazelcast member.

Notes

  • Additional fixed versions are available for enterprise users in 5.6.1 / 5.5.10 / 5.4.5 with the missing action bits covered.
