Salesforce announced that during a Marketing Cloud release between June 4 and July 7 of this year, a code change may have caused “a small subset of REST API calls to improperly retrieve or write data from one customer’s account to another.” The issue, discovered on July 18, was resolved the same day and affected customers were notified. The NJCCIC advises Salesforce Marketing Cloud customers to follow the Salesforce recommendations by carefully monitoring and reviewing their data to ensure nothing has been modified.
