CVE-2023-23638: Apache Dubbo vulnerable to Deserialization of Untrusted Data

The vulnerability explicitly occurs during 'dubbo generic invoke' per all advisory sources. GenericFilter is Dubbo's core handler for generic invocations and would be responsible for deserializing parameters. While no patch diffs are available, the consistent description of the attack vector (generic invoke deserialization) and Dubbo's architecture strongly implicate GenericFilter.invoke() as the entry point where unsafe deserialization would occur. The function's position in the RPC processing chain makes it the logical location for exploit triggering.
