CVE-2026-51368Network attack vector

Remote code execution via unsafe Java deserialization

Published Aug 25, 2026 · Updated Aug 25, 2026

Unsafe deserialization in TongWeb 7.0.24 allows remote attackers to execute arbitrary code through a crafted console/heimdall request. The exposed Spring HttpInvokerServiceExporter creates an ObjectInputStream and deserializes the request body without restricting object types. The published record does not state whether authentication is required; successful exploitation executes code in the TongWeb server process.
