Vulnerability

Field	Value
ID	V-002
Severity	CRITICAL
Scanner	multi_agent_ai
Rule	V-002
File	MMHelper/MMSocket/SocketServer/MMSocketClientItem.cpp:561

Description: The WebSocket frame parser performs four memcpy operations using length values derived directly from the incoming network frame header without validating that the source buffer contains sufficient data or that the destination buffer has adequate capacity. An unauthenticated remote attacker can send a malformed WebSocket frame with manipulated length fields to trigger out-of-bounds reads or writes, corrupting heap memory and potentially achieving remote code execution.

Changes
