CVE-2025-26866: Apache HugeGraph-Server: RAFT and deserialization vulnerability

December 12, 2025

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.
