If you visit Panera Bread's website today, you won't find the usual collection of sandwiches, soups, salads, and sausage rolls.

"Now, after I was reassured this would be fixed, I checked on this vulnerability every month or so because my own data is in there, which means I'm personally affected by it", Houlihan wrote.

According to Quartz, the data leak was discovered past year by Dylan Houlihan, the managing principal of New York-based Breaking Bits, a "data mining, reverse engineering and security consulting practice".

KrebsOnSecurity stated the site was still leaking data as of this week. Eventually, the Panera executive said they were working to fix the problem.

Following the blog post, Panera denied the estimation from Krebs that millions of customer records might be at risk.

"The flaw never disappeared", Houlihan told KresbsOnSecurity.

@onsecurity now believes up to 37 million customer records may have been affected.

A representative from Panera did not respond immediately to a request for comment from MONEY.

Reuters is reporting that Panera Bread is saying that the issue has been resolved.
