Probably not that dangerous. The ethanol has likely evaporated leaving behind vinegar and unpleasant byproducts. There’s a risk of mold and bacterial contamination depending on how well the seal has remained intact. Depending on the process used, it’s possible the wine could contain lead salts (for sweetness), which are toxic. I doubt it would kill you, but it’d likely be very unpleasant to drink.
