           Summary: View-source iframes are dangerous (and not very
                    useful).
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: ASSIGNED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: tsepez at chromium.org

Upstreamed from https://code.google.com/p/chromium/issues/detail?id=196636.

Memorable comments from that bug:
Collin: "View-source iframes seem dangerous in general; create a "captcha" that steals CSRF tokens, for example."
Justin: "We specifically disallow navigation to view-source URLs because we consider them unsafe. So allowing them via an iframe attribute is just a short trip to crazytown, population Chrome."
Adam: "It's non-standard and not supported by other browsers, AFAIK."

Platforms should have the option of excluding them, if they so desire.
