CVE-2025-32897Network attack vector

Remote code execution via unrestricted Raft deserialization

Published Jun 28, 2025 · Updated Mar 30, 2026

Deserialization in Apache Seata Server 2.0.0 through 2.2.0 allows remote attackers to execute code through crafted Raft data. RaftSyncMessageSerializer.decode passes synchronization bytes to ObjectInputStream.readObject without restricting resolved classes. Exploitation requires access to the internal network and the optional, non-default Raft cluster mode, and successful exploitation runs code on the server.
