Technical writeup
DocuSign user information was discovered to be accessible through a Google search. The information goes as far back as January 2012, and some information could be even older. It is possible to see private emails, signatures, times, dates, locations, addresses, document names, and email addresses. DocuSign claims that the information is available because a small number of DocuSign users have saved their own personal copies of their signed documents to publicly accessible and searchable location
