Same with the threads on the OP/s joint. The superglue suggested would only work as loctite not really structurally.

If it's loose, take the collar off, clean out old epoxy, do the same with the threads on the tennon. Glue in place with a quality epoxy. Most likely you want have to face the cue off at all. CA on cues and instruments is a PITA as it makes repair very difficult due to the chemical nature of CA and it's high melting point.
If it didn’t need glue why did it come loose?

The biggest worry I would have with super glue is that it could set before the collar is fully tightened down. SG sets very quickly when pressure is applied.

The thought on that was a couple drops at the joint face and leave the threads alone for now. If it comes loose again you are not out anything. The threads themselves are a mechanical bond without any adhesive as long as it doesn't unscrew. Just like nuts and bolts everywhere else in the world. It would be like putting a couple drops on your joint face and screwing on your shaft. Anyone want to try to take that apart anytime soon if done?
When this happens, even on cheap cues, I remove it, clean all the old crappy glue off, then screw it back together and using a grease pencil put a witness mark on the forearm and the collar...remove it and grind a slot in the threads aligned with the pencil mark on both the forearm and collar. I then screw a very small dia. delrin sleeve over the pin so no epoxy gets in the threads, or the pilot hole. Then I apply epoxy to both pieces and screw it on tight. Clean up the squeeze out, wait until the epoxy is thickened then remove the delrin sleeve. When dried, the 2 ground slots I cut will be filled with cured epoxy acting like a key to prevent it from coming loose if the epoxy lets go over time. I charge my 1 hr. shop rate for this job.
I could never bring myself to do this kind of slotting. Especially in threads. If the adhesive bond breaks down to the point of needing it, wouldn't it be better for it to just come all the way loose so it can be properly repaired?
Maybe somebody left the cue in their trunk in the hot summer heat?
I hope they didn't use Elmer's school glue
Many yrs ago, Dickie Neighbors pm'ed me that trick as, what he called the insurance plan. First, clean every thing of old glue, use a V file to abride the forearm threads and clean the SS collar threads with acetone before glueing. His idea was that if you do those steps, the key way was not needed, BUT if the cue was left in a hot car, etc. it had the key to keep it from ever moving. Have used it since then, and have not had any repeats come back. Literally, it takes about 4 minutes with a dremel tool with an 1/8 th endmill in it

What is the problem with super glue? I guess, not being a cue maker, I'm not understanding the subtleties of adhesives. I think it's pretty popular in guitar repair, but that's often for fixing chips instead of assembly. Some people put a drop under the frets when they install them to hold them in tight.
I think super glue in the construction of cues is GREAT!
If you want to eventually go back and do it again. Lol
Do it right the first time and be done with it.
Just my opinion of course. I've seen some pretty stupid things.

I put those key ways on every joint and butt cap I thread.
