This paper points out a security loophole in the Quantum key distribution with limited classical Bob [Int. J. Quantum Inf. 11(01) (2013) 1350005]. With the loophole, an eavesdropper can perform the double CNOT attack to reveal about n/4-bits out of an n-bit key without being detected by the protocol.
