A new security vulnerability has been discovered in the latest version of Apple’s Mojave software. The vulnerability is unpatched at the time of writing and impacts all versions of Mojave. Certain folders in Mojave have restricted access that is forbidden by default, like ~/Library/Safari, which can be accessed by only a few applications, such as Finder. An app with the ability to spy on Safari could be ‘notarized’ by Apple, researcher Jeff Johnson says. Since the vulnerability has already been reported to Apple, the vulnerability would not get a patch until at least the next official release.
