An example using only existing game mechanics:
You find one of these unstable wormholes in a neutron star solar system. Upon traversing the unstable wormhole and entering the dungeon solar system, an eminent collapse countdown started and announced by the crew. One week after the dungeon solar system is first entered it will be violently destroyed by a supernova or something. The dungeon solar system will be disconnected and unreachable in any other way than by the unstable wormhole.
Most worlds in the dungeon solar system will have a pirate base, spawning pirate ship encounters and such. Once the pirates are dealt with the dungeon solar system will function much the same as any other solar system, untill it is destroyed of course. Resource qualities would be higher than normal, giving an incentive to use harvester spacecraft or make some temporary mining colonies and using broker shipments to get the resources out.
For some added tension, other players finding new unstable wormholes could end up connecting to existing dungeon solar systems, creating a new wormhole connection to where they entered from. Meaning that the two players would have to either share or fight over the dungeon solar system.
For those of you that have played EVE Online you can think of it as W-space, and those if you who have played Stellaris can think of it as the L-cluster.
