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 Improper Input Validation via the client process. An attacker can read arbitrary memory from any cluster member, potentially access sensitive data, cause cluster members to crash, or corrupt memory contents, which may lead to remote code execution, by sending crafted requests from a low-privileged client.
** Notes: **
- Additional fixed versions are available for enterprise users in 5.6.1 / 5.5.10 / 5.4.5.
