The error was in production between June 4 to July 18, and potentially affected users of two modules within the broader Marketing Cloud offering, the Email Studio and Predictive Intelligence solutions.
“On July 18, we became aware of an issue that impacted a subset of Marketing Cloud customers using Marketing Cloud Email Studio and Predictive Intelligence.” reads the notice published by Salesforce.
“We resolved the issue on that same day, July 18. Customers who may have been impacted were notified. For additional details, please see the Email Studio and Predictive Intelligence REST API Issue article here: https://sfdc.co/XIbG2”
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.
