I’d say it’s about as safe as cliff diving or quarry diving into water. For safety reasons, make sure that the area you are jumping from is clear of any obstacles (don’t jump over bushes or if the ledge isn’t flush with the water) and that the water is sufficiently deep for your dive (at least 5 meters/15 ft for a safe dive). Also, if you are not familiar with the jump or not experienced with diving, you may just consider jumping feet-first to minimize hurting yourself. Finally, if the height of the jump is excessively high, you can still hurt yourself from the accelerate impact of you hitting the water. A 10 meter (~33 feet) jump can be made safely if you enter the water feet first. Higher than that and you start to risk injury. Other than that, just make sure you have good lighting and don’t jump into water that you can’t see into.
Cave diving and penetration wreck diving are more or less the same. Matter of fact the equipment used in wreck diving came from the pioneers of cave diving. Same with the techniques used.
Like anything in diving, it’s all about manageable risk. It’s as safe or as dangerous as the diver makes it. A properly equipped and trained cave diver, employing that skill set and equipment used responsibly is as safe as any other safe diver is. You’ll find more fatalities or injuries happening to basic open water divers and they dive in a “safer” environment because they have ignored basic rules. There’s an old saying about aircraft pilots that applies here too:
“There are old pilots and there are bold pilots. There are no old, bold pilots”.
It’s true here too.
An overwhelming number of cave accidents are by divers that have not received the proper training or experience. Nothing in cave diving is rocket science, but there have been 30+ years of experience to build upon.
As scubabob pointed out, with training and experiece, it is a very manageable risk. Without that training and experience it is a recipe for disaster.

Very dangerous without cave training, after cave training, not as dangerous as driving a car.
