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

[VGalaxies <vgalaxies () apache org>]

Severity: moderate

Affected versions:

- Apache HugeGraph-Server 1.0.0 ~ 1.5.0 (before 1.7.0)

Description:

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.
