Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache HugeGraph-Server's hg-pd-core package, versions before 1.7.0, is vulnerable to remote code execution through insecure Hessian deserialization in the PD store. An attacker who can act as a malicious Raft node can exploit this to run code. Upgrade to hg-pd-core 1.7.0, which adds IP-based authentication for cluster membership and a strict class whitelist for Hessian deserialization.
