CVE-2015-1304
object-observe.js in Google V8, as used in Google Chrome before 45.0.2454.101, does not properly restrict method calls on access-checked objects, which allows remote attackers to bypass the Same Origin Policy via a (1) observe or (2) getNotifier call.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
