CVE-2024-56180Network attack vector

Unauthenticated code execution via Hessian message deserialization

Published Feb 14, 2025 · Updated Feb 18, 2025

Unsafe deserialization in Apache EventMesh allows remote attackers to execute arbitrary code through crafted Hessian RPC messages. The eventmesh-meta-raft plugin deserializes attacker-controlled RPC messages with Hessian; Apache has not published the specific handler or patch diff. The network path requires no authentication or user interaction, and affected package versions begin at 1.10.1 and end before 1.11.0.
