+            &lt;rdar://problem/11187315&gt;
+
+            Reviewed by Tim Horton.
+
+            Check URLs sent from the web process before putting the on pasteboard.
+
+            * UIProcess/Cocoa/WebPasteboardProxyCocoa.mm:
+            (WebKit::WebPasteboardProxy::setPasteboardPathnamesForType):
+            Add a check to make sure the URLs we've received are valid and not compromising to the user's system.
+
+            * UIProcess/WebPasteboardProxy.cpp:
+            (WebKit::WebPasteboardProxy::addWebProcessProxy):
+            Keep track of the webProcesses associated with the pasteboard proxies specifically, so that we can
+            use it to check the URLs before putting them on pasteboard.
+            (WebKit::WebPasteboardProxy::removeWebProcessProxy):
+            Remove dead webProcesses.
+
+            * UIProcess/WebPasteboardProxy.h:
+            * UIProcess/WebPasteboardProxy.messages.in:
+            Allow for the connection to be passed in, so that we can determine which webProcess we need to
+            check the URLs of.
+
+            * UIProcess/WebProcessProxy.cpp:
+            (WebKit::WebProcessProxy::~WebProcessProxy):
+            Make sure to remove WebProcessProxys from the list stored in WebPasteboardProxy
