CVE-2016-1622
The Extensions subsystem in Google Chrome before 48.0.2564.109 does not prevent use of the Object.defineProperty method to override intended extension behavior, which allows remote attackers to bypass the Same Origin Policy via crafted JavaScript code.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
