How can I secure this metal 1-gang electrical box without creating a bigger hole?
I removed wood paneling in a room to reveal shoddy plaster & lath. I covered it with 3/8 in. drywall. I now need to add spacers to electrical outlets and a light switch.
Except for this one electrical outlet that was never fully secured to begin with. (I'm guessing the previous owner secured it to the lath that is now broken/missing?):

Much as I love metal boxes, don't consider that one to be the holy grail. Not least, one where the cables go in the end of the box will be more desirable because it will be easier to fit in the hole. Come to think of it, this might be a great time to go for a bigger box that'll fully use the hole's space, e.g. A 4x4 or even a 120mm (4-11/16) square.c

What you need is a metal old work box this has adjustable clamps that hold on the sheetrock. There are cheap plastic ones and better quality metal ones you will want one with clamps to do it right as those conduits are not clamped and they should be. You can add clamps to 1 end and work the box into the hole then tighten the wings
Excellent! TIL "old work" is an actual term used in the naming of electrical boxes made for this exact purpose.

You are going to need metal tabs that go behind the drywall then fold into the box to keep it secure.
These tabs are strong, but kind of harder to get installed.
You will have to take the plug out to make room to fold the tabs inside the metal box.
While you are in there, you really need a clamp to hold each wire to the box. (only one wire per knockout).
If there is room bringing the wires in from the back of the box will make is much easier to slip into the hole in the wall.
with e wire properly secured to the box, Start by slipping the tabs behind the wall and plaster. Now put the box in and bend the tabs inside the box. Reinstall the plug and you are done.
If you were not dealing with armored cable a new plastic rework box (home depot link) would arguably be the easiest sulition.

That's one way of doing it, and was the first thing that I thought of before I posted my answer. But those little buggers are not only difficult to work with, but they have sharp edges. Having said that, the old ones I have look different.

The simplest way is to replace that box with one that has flanges on each end (and built-in clamps in the back for that flex conduit). The flanges have holes for #6 flathead screws.
Drill a small pilot hole* for each of the four screws through the plaster and into the lath, and simply screw it to the wall.
- The diameter of the drill should be equal to --or a little smaller-- than the root (smallest) diameter below the threads themselves. That'll be near the tip of the threads.
