The Hidden Gateway: How Agent Tool Calls Enable Full System Compromise

LangGraph's vulnerability chain exposes a fundamental security blind spot in agentic AI frameworks. Attackers can leverage prompt injection to manipulate agent tool-calling behavior, bypassing traditional security defenses never designed to protect against this attack class. As organizations increasingly deploy autonomous agents on self-hosted infrastructure, this incident reveals that existing security models cannot address threats at the semantic layer between model output and tool execution.
