A Dozen Flaws in Popular Mac Clean-Up Software Allow Local Root Access

A passel of privilege-escalation vulnerabilities in MacPaw’s CleanMyMac X software would allow a local attacker to gain root access to an Apple machine in various ways.

No fewer than a dozen flaws plague 4.0 and earlier versions of the software, all of them in the package’s “helper protocol.”
