Quantum secret sharing is an important technique in the field of quantum cryptography. However, the existence of imperfect detector is a serious threat in practical. Here we propose a continuous-variable measurement-device-independent quantum secret sharing protocol to remove the attacks carried out on imperfect detectors. We analyze the performance of the proposed protocol under different conditions, and show that it can be extendable to a large number of participants, which is of great help to its practical implementation.
