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]
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.
An Integration object doesn't need access to the context dict used
to render its doc.md, since the context dict is just passed directly to
render_markdown_path.
Previously, when rendering a single integration, we tacked on the
following information to the context dict that was redundant:
* An OrderedDict containing all of the Integration objects for
all integrations.
* An OrderedDict containing all of the integration categories.
The context dict for rendering a particular integration doc would
contain 4 OrderedDicts, 2 for categories, 2 for Integration objects
because of how many times add_integrations_context had been called.
This was very wasteful, since an Integration object doesn't need
to access any other Integration object (or itself for that matter)
to render its documentation. This commit adds a function that
allows us to only pass in the context values that are necessary.
This often can cause minor caching problems.
Obviously, it'd be better if we had access to the AST and thus could
do this rule for UserProfile objects in general.
Instead of populating the context dict with integration-specific
information in render_markdown_path, we now do that in
zerver.views.integrations.integration_doc instead.
Fixes#7401.
Tweaked by tabbott to use cast to handle the typing issues here.
This endpoint will allow us to add/delete emoji reactions whose emoji
got renamed during various emoji infra changes. This was also a
required change for realm emoji migration.
This commit was tweaked significantly by tabbott for greater clarity
(with no changes to the actual logic).
