## Overview

A remote code execution vulnerability exists where a malicious Raft node can exploit insecure Hessian deserialization within the PD store. The fix enforces IP-based authentication to restrict cluster membership and implements a strict class whitelist to harden the Hessian serialization process against object injection attacks.




Users are recommended to upgrade to version 1.7.0, which fixes the issue.

## Affected

- `hugegraph >= 1.0.0, < 1.7.0`

## Remediation

Upgrade past the affected range:

- `hugegraph 1.7.0`
