Obviously this is not going to be a common thing, and common.js is
closely watched. (The above edit was reverted in 7 minutes, and the

There's an old post of mine that documents some of the ways to inject
I believe, as Brian notes in this thread, that most methods require having
the "editinterface" user right so that you can edit wiki pages in the
"MediaWiki" namespace. By default, this user right is assigned to the
"sysop" user group, but if you search through
<https://noc.wikimedia.org/conf/InitialiseSettings.php.txt> for the string
"editinterface", you can see that on specific wikis such as fawiki, this
user right has been assigned to additional user groups.

You could file a Phabricator task about this. We already specifically
exempt certain pages, such as Special:UserLogin and Special:Preferences,
preference to do what you're suggesting.
That said, you're currently executing thousands upon thousands of lines of
code on your computer that you've never read or verified. If you're a
standard computer user, you visit hundreds of Web sites per year that each
execute thousands of lines of untrusted scripts that you've never read or
verified. Of all the places you're likely to run into trouble, Wikimedia
wikis are, in many ways, some of the safest. Given all of this code, your
computer, as well as mine, are vulnerable to dozens of very real attacks
at any time. And yet we soldier on without too much panic or worry.
Has this sort of thing happened before?

This situation on fa.wikipedia.org
was obviously involuntary. I don't know
of any similar incidents. We have had wiki administrators inadvertently
inject scripts with privacy issues, such as Google Analytics. These
scripts have generally been promptly removed when noticed. On the other
hand, pages such as <https://status.wikimedia.org/> have been loading the

Can we be sure there isn't a gadget, interface page
that has this sort of
code lurking inside? Do we have any detection measures in place?
A much surer bet is that at least some gadgets and other site-wide
be shocking if, across the hundreds of Wikimedia wikis, none of them did.
I think in the past Timo and maybe Alex Monk have done some surveying of
public Wikimedia wikis using a browser or browser emulator to check if
there are network requests being made to non-Wikimedia domains. As Lucas
noted in this thread already, there are also tasks such as
<https://phabricator.wikimedia.org/T135963> that could be worked on, if
there's sufficient interest.
