A new vulnerability fundamentally breaks zerocoin security.

I don't see why it can't be fixed if true.

Looks like the Zcoin developers are not going to bother fixing it.
I suppose the burden is placed on VEIL devs now.

Although we believe that Zerocoin can be fixed given sufficient time, we have decided not to dedicate further resources to it. This is in line with our roadmap to transition away from Zerocoin to Sigma, which has no trusted setup, security proofs for all its proof systems, and it has a much simpler construction along with its performance benefits.
Also looks like PIVX is transitioning away from the Zerocoin protocol instead of fixing the vulnerability:
