I recall someone creating a crypto system and then forgetting to protect the constructor of the initial object so other could change the constructor and do whatever they wanted with that crypto system, but in the end the creators were just web developers with a little training in crypto.

In those circumstances those millions of coins flying in or out are not a tragedy (at least for me) but a very plausible outcome.

That's a completely different and unrelated type of vulnerability, though.

Implementation mistakes leading to mass coin theft would certainly be cryptocurrency news, but they would not be crypto(graphy) news. Breaking an actual peer-reviewed zero knowledge proof scheme would be.
