This vulnerability, CVE-2025-53015, targets the HugeGraph-Server’s RAFT-based PD (Placement Driver) store. The cluster communication for metadata uses the Hessian protocol for Java object serialization/deserialization. The flaw exists because the deserialization process lacks proper validation, accepting any serialized object without a restrictive class whitelist. A malicious actor, by compromising or spoofing a legitimate Raft node, can send crafted Hessian data to the PD store endpoint. When this malicious payload is deserialized, it triggers the execution of arbitrary Java code on the server. This remote code execution (RCE) is possible due to gadget chains present in the application’s classpath, which allow deserialization to become a vehicle for command injection. The fix involves two key changes: enforcing IP-based authentication for Raft peer communication to prevent unauthorized node joining, and implementing a strict, minimal whitelist for allowed classes during Hessian deserialization, thereby neutralizing the object injection attack vector.
