The news was first reported by BankInfoSecurity that obtained a copy of the alert distributed by the company via email on Thursday.

Salesforce states that the error involved the company’s REST application programming interface.

“During a Marketing Cloud release between June 4, 2018, and July 7, a code change was introduced that, in rare cases, could have caused REST API calls to retrieve or write data from one customer’s account to another inadvertently,” reads the alert issued by Salesforce and published by BankInfoSecurity.

“Where the issue occurred, the API call may have failed and generated an error message rather than writing or modifying data.”

The company also warns that some customers may have had their data corrupted, it has also posted a knowledge article on the issue.

The bad news for the customers of the company. is that at the time it is not able to say if data was altered or is attackers maliciously tampered with.

“We have no evidence of malicious behavior associated with this issue,” a Salesforce spokesman told ISMG.

“We are unable to confirm if your data was viewed or modified by another customer,” Salesforce explained in its alert, noting that it was notifying all customers just to be on the safe side. “While Salesforce continues to conduct additional quality checks and testing in relation to this issue, we recommend that you monitor and review your data carefully to ensure the accuracy of your account.”
