This article details "CutBackdoor," a novel supply-chain attack targeting Variational Quantum Algorithms (VQAs) that exploits the standard circuit cutting technique required when quantum hardware capacity is exceeded. The vulnerability allows malicious parameters to remain dormant until deployment, triggering an energy amplification of 1.3× to 2.9× specifically within cut paths without altering the underlying circuit logic or requiring active attacker presence at runtime. This discovery highlights a critical structural weakness in current VQA security models where necessary optimization workflows inadvertently create new attack surfaces for parameter poisoning.
