In a more detailed disclosure, the company further elaborated the following:

During a Marketing Cloud release that was rolled out between June 4, 2018 and July 7, a code change was introduced that may have caused a small subset of REST API calls to improperly retrieve or write data from one customer’s account to another.

The Salesforce Security team became aware of the issue on July 18, 2018. An emergency release (eRelease) was deployed at 5:00 UTC on July 18, resolving the issue for all Marketing Cloud stacks. We have no evidence of malicious behavior associated with this issue.
