The breach occurred on Wednesday, a DNC official confirmed, through the NGP VAN, the leading technology company that allows campaigns to identify voters, as well as monitor their preferences and leanings, in what’s called the 50-state voter file. For a “brief window” — about 30 minutes, an official said — a bug in the software exposed the campaigns’ internal “voter ID” data.
During that period, the Sanders campaign discovered the breach, accessed the Clinton campaign’s data, then called the vendor to point out the flaw, according to the official. The DNC has since cut off Sanders’s access to the voter file — until his campaign officials can “prove” they’ve deleted the Clinton data.

“On more than one occasion, the vendor has dropped the firewall between the data of different Democratic campaigns,” he said. “Our campaign months ago alerted the D.N.C. to the fact that campaign data was being made available to other campaigns. At that time our campaign did not run to the media, relying instead on assurances from the vendor.”www.nytimes.com/... No good deed goes unpunished. The DNC blocked Bernie's campaign from accessing their own data after they reported the bug. Meanwhile the Hillary campaign might have accessed Bernie's files and they still have access to the database. BTW the vendor’s CEO was the CTO of the Hillary 2008 campaign.
