I am reading on the Zencash threat that there is a vulnerability in both ZEN and ZCL.  The ZEN developers have decided to implement a soft fork and have released new node software to resolve the issue.  They are saying the same issue exists in ZCL and this is why Bittrex has frozen the wallets of both currencies.

Can someone confirm if this is true and if so, if ZCL development working on a solution for ZCL?
