            Bug ID: 153889
           Summary: CustomGetterSetter accessors should only work on
                    objects from the same global object
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org

In order to be safe from information leakage we should make the CustomGetterSetter functions require that the |this| object and the argument (in the case of setters) be from that same origin as the getter/setter function itself.

This is simply a guaranteed hardening against leakage, and as we haven't historically exposed this kind of information it can't be a regression.
