Leaking vent pipe?

Can this be happening? I have water coming through my 2nd floor bathroom ceiling. When looking at it from the attic the water appears to be coming from a joint in the PVC toilet vent pipe which runs along above the bathroom ceiling. The pipe is vented through the roof about 15 feet from this joint. Is it normal for this pipe to have water in it? How do I stop this leak?

The pipe could have moisture in it from rain or condensation. Of course, it should not leak. The fitting should be cut out and replaced.

Look closely to ensure it is not water leaking through the roof around the outside of the pipe, and running down.

Most vent pipes aren't covered so they can accumulate rainwater in a horizontal run that isn't sloped. There is a possibility that the joint is just fit together without glue. If not, another option is repair tape sold at most big boxes. Since the pipe will never see pressure the tape should do the job.
