How bad is this on a subwoofer and can it be repaired without much degradation?

Monoprice use nitrile rubber for their woofer surrounds. Whether you can find an adhesive that can bond to that and stays flexible enough to withstand the violent movement in the long term, I don't know. I have my doubts.
I doubt Monolith can help with a repair kit in any case, even a replacement driver they may not have. Maybe you can repair it as mentioned, but I also have my doubts (and tried once upon a time with a mid-woofer and failed). Maybe contact a dedicated speaker repair outfit....

I would give it a try with RTV or maybe hot glue. You are unlikely to make things worse.
If you replace the woofer, try to get the exact one, especially if it's a ported box because the box is "tuned" to work with the driver. And assuming it's an active sub, the amplifier might be EQ'd to optimize performance of that woofer in that box, even if it's a sealed design.
There are places that specialize in speaker "reconing. They can repair almost anything and it certainly won't cost $700.
Or you can by a different woofer and use the Theile-Small parameters with speaker design software to check the performance in the box, and maybe determine some port modifications, or the software will tell you if a ported or sealed design is better with a particular driver, etc.

Parts Express sells speaker surround repair kits. I used one once to redo foam surrounds on some 30 year old 18" Pyle drivers (back when they still made good stuff) and it worked well enough but I replaced the drivers within a year after that so can't speak to how long lasting the adhesive in the kit is.
I'd patch it.
A little piece of bicycle innertube and some contact cement.
Maybe patch it from the backside for appearance if not using a grill.
