It is likely the "operative" - "source" is misleading to make think it is a character. It could very well be something else. For example, just a few frames before when the light was speaking among themselves about the operative inside, cheshire's mask was taken as a souvenir (she might have faked it was knocked off and left it there on purpose), it could have some kind of beacon whatever. The g-nome - Superboy link could also work, but that kinda dulls it down since it was already used in the comic. Replying it again would be boring.

We have to also consider this, the moment the intel gets to JL, Batman would have them mind checked by MM in secret, so if the "inside source" is not Miss M then his/her cover is blown already. And it may also be possible that the went out of control exercise in Failsafe is actualy a stage to check if Miss M is ok (hence MM cannot mind check her) i.e. a real spy would have no part in such a battle if the purpose of his/her mission is no longer valid (the team disintigrated), a real spy would just bail out of the situation, but she stayed so that proves she is ok. Also to note, Failsafe happens just after Humaity where JL gets the intel so it could very well be a spy check rather than an exercise.

About Artemis "Red Herring", her background checks ok and proves she is very unlikely to be a mole and this is Earth-16, another reality than regular comics.... But there is an occasion in Bereft where she tells KF "this is ANOTHER of her father's stupid tests and he probably wants her to kill him"... While this may not indicate her to be mole for certain, it indicates she has a darker past (which includes assassination as training) and she very recently turned over to the right side from the wrong side i.e. reconsidered her life, morals kicked in whatever... So in the comics per her thoughts we see her as a real valid good guy. In the mean time it might be the usual threaten, "tell us or we tell them" thing (which would also be a boring cliche) with Artemis.
