Today, IBM has reported the discovery of a Dropbox vulnerability.  This vulnerability was found by IBM’s X-Force Application Security Team in the software development kit (SDK) for Android, and if exploited could have potentially allowed an attacker to connect to a harmful application on a victim’s mobile device, and would have let them gain access to personal information within private cloud drive.
