Twitter sent emails to its business customers alerting them that information may have been compromised.

The social network said in those emails that it initially learned of the problem May 20, adding that the bug, which has been resolved, caused business users’ billing information such as email addresses, phone numbers and the last four digits of credit-card numbers to inadvertently be stored in web browsers’ cache, meaning that it was possible that other people could access that data in cases where computers are shared.

Twitter senior communications manager Laura Pacas said, “We became aware of an incident where if you viewed your billing information on ads.twitter.com or analytics.twitter.com, the billing information may have been stored in the browser’s cache. As soon as we discovered this was happening, we resolved the issue and communicated to potentially impacted clients to make sure they were aware and informed on how to protect themselves moving forward.”

She would not specify how many customers may have been affected.
