SCA: security update for com.hazelcast:hazelcast (GHSA-6v25-8wq6-xq4j)

critical Tenable Cloud Security Plugin ID 473950

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Hazelcast is a unified real-time data platform combining stream processing with a fast data store. Prior
 to 5.4.5, 5.5.10, and 5.6.1, improper validation of data supplied by a malicious client able to connect to
 a cluster allows arbitrary reads from a cluster member's Java heap, off-heap data, and JVM process address
 space. The same flaw can crash cluster members and, in some Hazelcast Enterprise Edition configurations,
 corrupt memory with possible arbitrary code execution. Both slim and full distributions are affected. This
 issue is fixed in versions 5.4.5, 5.5.10, 5.6.1, and 5.7.0. (CVE-2026-107726)

Solution

Update the com.hazelcast:hazelcast library and its related packages to version 5.7.0 or later.
