What are the dangers of wormholes?

Could you elaborate on the perils associated with wormholes? I'm particularly interested in understanding the potential risks they pose to both astrophysical objects and the theoretical framework of our universe. Could the existence of wormholes lead to the disruption of spacetime, or could they potentially provide a gateway to unknown and potentially dangerous regions of the cosmos? Additionally, how do physicists currently view the likelihood of encountering such phenomena in our observable universe? It would be fascinating to hear your thoughts on these matters.
