The Steam bug that allowed users to see other users' account details may not have been as harmful as it first appeared
. Valve said in a statement (reported on Mashable) that while cached data showed usernames, "sensitive details such as credit card numbers are automatically censored on user account pages, which mitigates the potential harm of someone having seen your personal data." From Mashable's report:
"Steam is back up and running without any known issues," Valve told Game Informer in a statement. "As a result of a configuration change earlier today, a caching issue allowed some users to randomly see pages generated for other users for a period of less than an hour. This issue has since been resolved. We believe no unauthorized actions were allowed on accounts beyond the viewing of cached page information and no additional action is required by users."
