In configurations with LDAP_APPEND_DOMAIN, we don't want people creating
non-ldap accounts with emails matching the ldap domain.
So in the registration flow, if the email isn't found in LDAP, but
matches LDAP_APPEND_DOMAIN, we stop, rather than proceeding with account
creation. In case of emails not matching LDAP_APPEND_DOMAIN, we will
still continue to make a normal, non-ldap account.
The problem was that, for example, given a configuration of social
backend + LDAPPopulator, if a user that's not in ldap was being
registered, the Full Name field in the registration form would be
empty instead of getting prefilled with the name provided by the
social backend.
This fixes it - first we try to get the name from ldap. If that
succeeds, a form is created pre-filled with that name. Otherwise, we
proceed to attempt to pre-fill with other means.
This also has a nice side effect of reorganizing most of the logic to
be more parallel between LDAP and other sources of name data.
This is a performance optimization, since we can avoid doing work
related to wildcard mentions in the common case that the message can't
have any. We also add a unit test for adding wildcard mentions in a
message edit.
Previously, the LDAP code for syncing user data was not
multiple-realm-aware, resulting in errors trying to sync data for an
LDAP user present in multiple realms.
Tweaked by tabbott to add some extended comments.
Fixes#11520.
For a long time, we've been only doing the zxcvbn password strength
checks on the browser, which is helpful, but means users could through
hackery (or a bug in the frontend validation code) manage to set a
too-weak password. We fix this by running our password strength
validation on the backend as well, using python-zxcvbn.
In theory, a bug in python-zxcvbn could result in it producing a
different opinion than the frontend version; if so, it'd be a pretty
bad bug in the library, and hopefully we'd hear about it from users,
report upstream, and get it fixed that way. Alternatively, we can
switch to shelling out to node like we do for KaTeX.
Fixes#6880.
A bug in Zulip's new user signup process meant that users who
registered their account using social authentication (e.g. GitHub or
Google SSO) in an organization that also allows password
authentication could have their personal API key stolen by an
unprivileged attacker, allowing nearly full access to the user's
account.
Zulip versions between 1.7.0 and 2.0.6 were affected.
This commit fixes the original bug and also contains a database
migration to fix any users with corrupt `password` fields in the
database as a result of the bug.
Out of an abundance of caution (and to protect the users of any
installations that delay applying this commit), the migration also
resets the API keys of any users where Zulip's logs cannot prove the
user's API key was not previously stolen via this bug. Resetting
those API keys will be inconvenient for users:
* Users of the Zulip mobile and terminal apps whose API keys are reset
will be logged out and need to login again.
* Users using their personal API keys for any other reason will need
to re-fetch their personal API key.
We discovered this bug internally and don't believe it was disclosed
prior to our publishing it through this commit. Because the algorithm
for determining which users might have been affected is very
conservative, many users who were never at risk will have their API
keys reset by this migration.
To avoid this on self-hosted installations that have always used
e.g. LDAP authentication, we skip resetting API keys on installations
that don't have password authentication enabled. System
administrators on installations that used to have email authentication
enabled, but no longer do, should temporarily enable EmailAuthBackend
before applying this migration.
The migration also records which users had their passwords or API keys
reset in the usual RealmAuditLog table.
This change makes it possible for users to control the notification
settings for wildcard mentions as a separate control from PMs and
direct @-mentions.
We move the check that the user is a member or admin inot this
decorator.
This name better communicates that this may do other checks beyond
just verifying the policy.
We'll be soon documenting a production workflow that involves using
it, and that means it needs to live under scripts/ (since tools/ isn't
present in release tarballs).
This is essentially an assertion failure code path, so it doesn't
really matter, but it seems best to use the value that's the cause of
the problem here.
Then, find and fix a predictable number of previous misuses.
With a small change by tabbott to preserve backwards compatibility for
sending `yes` for the `forged` field.

The original/legacy emoji reactions endpoints made use of HTTP PUT and
didn't have an API that could correctly handle situations where the
emoji names change over time. We stopped using the legacy endpoints
some time ago, so we can remove them now.
This requires straightforward updates to older tests that were still
written against the legacy API.
Fixes#12940.
The function only used the user's realm anyway, so this is a cleaner
API.
This should also make it more convenient to permanently delete
messages manually, since one doesn't have to fetch a random user in
the realm in order to delete a message using the management shell.
No functional change.
When creating realm with the ldap backend, the registration flow didn't
properly handle some things - the user wouldn't be set as realm admin,
initial subscriptions and messages weren't created, and the redirect
wasn't happening properly in the case of subdomains.
As discussed in the comment, ideally these checks should be added
completely automatically, rather than needing to be manually added
every time we add a new setting. But hopefully the example code for
all of the similar enums that this provides will at least provide some
help.
By adding some additional plumbing (through PreregistrationUser) of the
full_name and an additional full_name_validated option, we
pre-populate the Full Name field in the registration form when coming
through a social backend (google/github/saml/etc.) and potentially skip
the registration form (if the user would have nothing to do there other
than clicking the Confirm button) and just create the account and log
the user in.
The main purpose of this is to make that name change happen in
/server_settings. external_authentication_methods is a much better, more
descriptive name than social_backends from API perspective.
This small block of code was over-indented. It should be run in this
part of the function unconditionally, not inside an "else" block.
We obviously want it to run regardless of whether
request.POST.get('from_confirmation')
is True or not.
This legacy endpoint was designed for the original native Zulip mobile
apps, which were deprecated years ago in favor of the React Native
app.
It was replaced by /server_settings for active use years ago, so it's
safe to remove it now.
The url scheme is now /accounts/login/social/saml/{idp_name} to initiate
login using the IdP configured under "idp_name" name.
display_name and display_logo (the name and icon to show on the "Log in
with" button) can be customized by adding the apprioprate settings in
the configured IdP dictionaries.
This changes the way django_to_ldap_username works to make sure the ldap
username it returns actually has a corresponding ldap entry and raise an
exception if that's not possible. It seems to be a more sound approach
than just having it return its best guess - which was the case so far.
Now there is a guarantee that what it returns is the username of an
actual ldap user.
This allows communicating to the registration flow when the email being
registered doesn't belong to ldap, which then will proceed to register
it via the normal email backend flow - finally fixing the bug where you
couldn't register a non-ldap email even with the email backend enabled.
These changes to the behavior of django_to_ldap_username require small
refactorings in a couple of other functions that call it, as well as
adapting some tests to these changes. Finally, additional tests are
added for the above-mentioned registration flow behavior and some
related corner-cases.
Previously, the logic for determining whether to provide an LDAP
password prompt on the registration page was incorrectly including it
if any LDAP authentication was backend enabled, even if LDAP was
configured with the populate-only backend that is not responsible for
authentication (just for filling in name and custom profile fields).
We fix this by correcting the conditional, and add a test.
There's still follow-up work to do here: We may still end up
presenting a registration form in situations where it's useless
because we got all the data from SAML + LDAP. But that's for a future
issue.
This fixes a bug reported in #13275.
There are a few outstanding issues that we expect to resolve beforce
including this in a release, but this is good checkpoint to merge.
This PR is a collaboration with Tim Abbott.
Fixes#716.
Fixes#1727.
With the server down, apply migrations 0245 and 0246. 0246 will remove
the pub_date column, so it's essential that the previous migrations
ran correctly to copy data before running this.
Apparently, our change in b8a1050fc4 to
stop caching responses on API endpoints accidentally ended up
affecting uploaded files as well.
Fix this by explicitly setting a Cache-Control header in our Sendfile
responses, as well as changing our outer API caching code to only set
the never cache headers if the view function didn't explicitly specify
them itself.
This is not directly related to #13088, as that is a similar issue
with the S3 backend.
Thanks to Gert Burger for the report.
The previous code for ensuring the sort order of emoji choices was
correct relied on an OrderedDict structure, which isn't guaranteed to
be preserved when passed to the frontend via JSON (in fact, it isn't,
since we converted the way page_params is passed to use
sort_keys=True). Switch it to a list of dictionaries to correct this.
Fixes#13220.
