O2 has blocked a security hole that allowed its customers to view text messages sent by other UK subscribers online, reports The Register.
The problem involved O2's Bluebook application, which allows subscribers to save text messages they send or receive for viewing online.
But O2 coding errors in Bluebook allowed registered users to view other customers' messages and phone numbers, by simply changing the message ID number in URLs used to access messages on the site.
O2 told The Register it had fixed the problem.
