We took ChatGPT offline earlier this week because of a bug in an open-source library which allowed some customers to see titles from one other lively person’s chat historical past. It’s additionally attainable that the primary message of a newly-created dialog was seen in another person’s chat historical past if each customers have been lively across the similar time.
The bug is now patched. We have been in a position to restore each the ChatGPT service and, later, its chat historical past function, excluding just a few hours of historical past. As promised, we’re publishing extra technical particulars of this drawback under.
Upon deeper investigation, we additionally found that the identical bug might have triggered the unintentional visibility of payment-related data of 1.2% of the ChatGPT Plus subscribers who have been lively throughout a particular nine-hour window. Within the hours earlier than we took ChatGPT offline on Monday, it was attainable for some customers to see one other lively person’s first and final identify, e-mail deal with, cost deal with, the final 4 digits (solely) of a bank card quantity, and bank card expiration date. Full bank card numbers weren’t uncovered at any time.
We imagine the variety of customers whose information was truly revealed to another person is extraordinarily low. To entry this data, a ChatGPT Plus subscriber would have wanted to do one of many following:
- Open a subscription affirmation e-mail despatched on Monday, March 20, between 1 a.m. and 10 a.m. Pacific time. Because of the bug, some subscription affirmation emails generated throughout that window have been despatched to the flawed customers. These emails contained the final 4 digits of one other person’s bank card quantity, however full bank card numbers didn’t seem. It’s attainable {that a} small variety of subscription affirmation emails might need been incorrectly addressed previous to March 20, though now we have not confirmed any cases of this.
- In ChatGPT, click on on “My account,” then “Handle my subscription” between 1 a.m. and 10 a.m. Pacific time on Monday, March 20. Throughout this window, one other lively ChatGPT Plus person’s first and final identify, e-mail deal with, cost deal with, the final 4 digits (solely) of a bank card quantity, and bank card expiration date might need been seen. It’s attainable that this additionally might have occurred previous to March 20, though now we have not confirmed any cases of this.
We have now reached out to inform affected customers that their cost data might have been uncovered. We’re assured that there isn’t any ongoing danger to customers’ information.
Everybody at OpenAI is dedicated to defending our customers’ privateness and conserving their information secure. It’s a duty we take extremely critically.
