This issue is particularly important on Linux because many Linux users use a network file system, such as AFS or NFS, which maps the entire world into the local file system. For example, if I made my home directly world-readable, it's quite likely that I would be able to control this URL on your user's machines:
I notice that WebKitGTK+ disables this by default, good =).
Awesome. :)
I think, though, that the AFS/NFS issue you mention is more general and shouldn't be a motivating factor. We have many GNU/Linux users not in corporate networks, these days, as well, and I think we should not be designing everything for big installations (those usually have admins who can worry about this kind of issue).
Also, it looks like you can access windows shares using file://server/folder/file.html, so this doesn't seem to be UNIX-specific in any way. I also bet Mac can be made to use NFS, and AFS, so, again, I fail to see this as particularly important on non-Mac UNIX-likes.
I'm not sure I quite followed your line of reasoning here. Are you suggesting that everyone should use the more secure setting or are you saying that you don't think this is an important security measure in non-enterprise settings? I agree that everyone should disable universal access for file URLs. In fact, I think we should make it the default because the current default is pretty dangerous. Adam
