This completes the last commit's work to fix CVE-2017-0910, applying
to any invite links already created before the fix was deployed. With
this change, all new-user registrations must match an explicit realm
in the PreregistrationUser row, except when creating a new realm.
[greg: rewrote commit message]
We would allow a user with a valid invitation for one realm to use it
on a different realm instead. On a server with multiple realms, an
authorized user of one realm could use this (by sending invites to
other email addresses they control) to create accounts on other
realms. (CVE-2017-0910)
With this commit, when sending an invitation, we record the inviting
user's realm on the PreregistrationUser row; and when registering a
user, we check that the PregistrationUser realm matches the realm the
user is trying to register on. This resolves CVE-2017-0910 for
newly-sent invitations; the next commit completes the fix.
[greg: rewrote commit message]
Hides URL if the message content == image url so that sending gifs or
images feels less cluttered. Uses the url_to_a() function to generate
the expected url string for matching.
Fixes#7324.
Appends "Test: " text to some tests to make changes to the image preview
rendering. In the future, if the message is only a link to an image,
the link will be hidden.
Previously, this was a ValidationError, but that doesn't really make
sense, since this condition reflects an actual bug in the code.
Because this happened to be our only test coverage the ValidationError
catch on line 84 of registration.py, we add nocoverage there for now.
This deletes the old mock-covered test for this, which was mostly
useless. We have a much less messy test, which we extend to provide
the same test coverage the old one did.
While the result was the same before, this makes it more obvious.
This fixes a bug where, when a user is unsubscribed from a stream,
they might have unread messages on that stream leak. While it might
seem to be a minor problem, it can cause significant problems for
computing the `unread_msgs` data structures, since it means we need to
add an extra filter for whether the user is still subscribed, either
in the backend or in the UI.
Fixes#7095.
This code path was only required because we had remote_user set as a
positional argument here, and thus we'd be running this auth backend's
code when actually using another auth backend (due to how Django auth
backends are selected based on argument signature).
Inorder to provide more explicit error messages I have merged the
`emoji_code_is_valid()` and `emoji_name_is_valid()` functions into
`check_emoji_code_consistency()` and `check_emoji_name_consistency()`
respectively.
The installation admin is not the right person to get support requests from
deactivated users, regardless of the situation.
Also updates the wording to be a bit more concise.
This was basically rewritten by tabbott, because the code is a lot
cleaner after just rewriting the ZulipPasswordResetForm code to no
longer copy the model of the original Django version.
Fixes#4733.
