Pennsylvania Voter Services just fixed a serious security breach in their online voter registration process. As recently as 5:00 pm this afternoon, anyone downloading a blank voter registration card was provided a URL that included an ID number at the end which could be edited to access thousands of filled out voter registration cards. The PA authorities were alerted to this problem, and within about 30 minutes, the problem was fixed. URLs that previously accessed filled out (but not signed) .pdf's of voter registration cards (see redacted image) now return an "invalid request" message.
