Cybozu: newsletter recipient emails may have leaked via Cuenote FC breach

概述

Possible fields: newsletter recipient emails and similar. No count (count blank). No impact on data held in Cybozu services such as kintone. This stems from the Ymir Link Cuenote FC intrusion (recorded separately); the figure is a subset of the vendor scope and must not be added to it.
