This adds the Silence Reason column to silenced user lists.
This feature helps combat large spam attacks cause you can quickly see
why a user was silenced and then bulk act on all the silenced users
This commit introduces a new feature that allows staff to bulk select and delete users directly from the users list at `/admin/users/list`. The main use-case for this feature is make deleting spammers easier when a site is under a large spam attack.
Internal topic: t/140321.
This patch replaces the parameters provided to a service through
`params` by the contract object.
That way, it allows better consistency when accessing input params. For
example, if you have a service without a contract, to access a
parameter, you need to use `params[:my_parameter]`. But with a contract,
you do this through `contract.my_parameter`. Now, with this patch,
you’ll be able to access it through `params.my_parameter` or
`params[:my_parameter]`.
Some methods have been added to the contract object to better mimic a
Hash. That way, when accessing/using `params`, you don’t have to think
too much about it:
- `params.my_key` is also accessible through `params[:my_key]`.
- `params.my_key = value` can also be done through `params[:my_key] =
value`.
- `#slice` and `#merge` are available.
- `#to_hash` has been implemented, so the contract object will be
automatically cast as a hash by Ruby depending on the context. For
example, with an AR model, you can do this: `user.update(**params)`.
Currently, when calling a service with its block form, a `#result`
method is automatically created on the caller object. Even if it never
clashed so far, this could happen.
This patch removes that method, and instead use a more classical way of
doing things: the result object is now provided as an argument to the
main block. This means if we need to access the result object in an
outcome block, it will be done like this from now on:
```ruby
MyService.call(params) do |result|
on_success do
# do something with the result object
do_something(result)
end
end
```
In the same vein, this patch introduces the ability to match keys from
the result object in the outcome blocks, like we already do with step
definitions in a service. For example:
```ruby
on_success do |model:, contract:|
do_something(model, contract)
end
```
Instead of
```ruby
on_success do
do_something(result.model, result.contract)
end
```
This commit introduces a feature that allows an admin to delete a user's
associated account. After deletion, a log will be recorded in staff
actions.
ref=t/136675
- fetch models inside services
- validate `user_id` in contracts
- use policy objects
- extract more logic to actions
- write specs for services and action
This patch removes the `with_service` helper from the code base.
Instead, we can pass a block with actions directly to the `.call` method
of a service.
This simplifies how to use services:
- use `.call` without a block to run the service and get its result
object.
- use `.call` with a block of actions to run the service and execute
arbitrary code depending on the service outcome.
It also means a service is now “self-contained” and can be used anywhere
without having to include a helper or whatever.
This commit moves the business logic in the `Admin::UsersController#suspend` and `Admin::UsersController#silence` actions to dedicated service classes. There's no functional changes in this commit.

This commit fixes a bug where the silence button is incorrectly displayed on the admin page of a staff user. It's not actually possible to silence a staff user because the backend correctly prevents it, but the frontend isn't checking if the button should be displayed.
Another small bug that this commit fixes is the similar users list not showing up inside the silence/suspend modals due to also a bug in the frontend.
I've also changed the way similar users are loaded so that they're not returned by the `admin/users#show` endpoint anymore and moved them into a new endpoint that the penalize modals (suspend and silence) can call directly to retrieve the list of users. This is done because the similar users list is never shown on the admin user page (`/admin/users/:user_id/:username`); they're only needed when the suspend or silence modals are opened.

In some admin user controller extensions, @user is used to derive certain values.
The grant_admin method requires @user as well, so we are adding it here. This is tested in the plugin that it is used in.
This commit operates at three levels of abstraction:
1. We want to prevent user history rows from being unbounded in size.
This commit adds rails validations to limit the sizes of columns on
user_histories,
2. However, we don't want to prevent certain actions from being
completed if these columns are too long. In those cases, we truncate
the values that are given and store the truncated versions,
3. For endpoints that perform staff actions, we can further control
what is permitted by explicitly validating the params that are given
before attempting the action,
* FEATURE: Show similar users when penalizing a user
Moderators will be notified if other users with the same IP address
exist before penalizing a user.
* FEATURE: Allow staff to penalize multiple users
This allows staff members to suspend or silence multiple users belonging
to the same person.
Currently, moderators are able to set primary group for users
irrespective of the of the `moderators_manage_categories_and_groups` site
setting value.
This change updates Guardian implementation to honour it.
* DEV: Add a dedicated Admin::StaffController base controller
The current parent(Admin:AdminController) for all admin-related controllers
uses a filter that allows only staff(admin, moderator) users.
This refactor makes Admin::AdminController filter for only admins as the name suggests and
introduces a base controller dedicated for staff-related endpoints.
* DEV: Set staff-only controllers parent to Admin::StaffController
Refactor staff-only controllers to inherit newly introduced
Admin::StaffController abstract controller. This conveys the
purpose of the parent controller better unlike the previously used parent
controller.
When calling the API to delete a user:
```
curl -X DELETE "https://discourse.example.com/admin/users/159.json" \
-H "Content-Type: multipart/form-data;" \
-H "Api-Key: ***" \
-H "Api-Username: ***" \
-F "delete_posts=true" \
-F "block_email=false" \
-F "block_urls=false" \
-F "block_ip=false"
```
Setting the parameters `block_email`, `block_urls` and `block_ip`explicitly to `false` did not work because the values weren't being parsed to boolean.
2FA support in Discourse was added and grown gradually over the years: we first
added support for TOTP for logins, then we implemented backup codes, and last
but not least, security keys. 2FA usage was initially limited to logging in,
but it has been expanded and we now require 2FA for risky actions such as
adding a new admin to the site.
As a result of this gradual growth of the 2FA system, technical debt has
accumulated to the point where it has become difficult to require 2FA for more
actions. We now have 5 different 2FA UI implementations and each one has to
support all 3 2FA methods (TOTP, backup codes, and security keys) which makes
it difficult to maintain a consistent UX for these different implementations.
Moreover, there is a lot of repeated logic in the server-side code behind these
5 UI implementations which hinders maintainability even more.
This commit is the first step towards repaying the technical debt: it builds a
system that centralizes as much as possible of the 2FA server-side logic and
UI. The 2 main components of this system are:
1. A dedicated page for 2FA with support for all 3 methods.
2. A reusable server-side class that centralizes the 2FA logic (the
`SecondFactor::AuthManager` class).
From a top-level view, the 2FA flow in this new system looks like this:
1. User initiates an action that requires 2FA;
2. Server is aware that 2FA is required for this action, so it redirects the
user to the 2FA page if the user has a 2FA method, otherwise the action is
performed.
3. User submits the 2FA form on the page;
4. Server validates the 2FA and if it's successful, the action is performed and
the user is redirected to the previous page.
A more technically-detailed explanation/documentation of the new system is
available as a comment at the top of the `lib/second_factor/auth_manager.rb`
file. Please note that the details are not set in stone and will likely change
in the future, so please don't use the system in your plugins yet.
Since this is a new system that needs to be tested, we've decided to migrate
only the 2FA for adding a new admin to the new system at this time (in this
commit). Our plan is to gradually migrate the remaining 2FA implementations to
the new system.
For screenshots of the 2FA page, see PR #15377 on GitHub.
This commit adds token_hash and scopes columns to email_tokens table.
token_hash is a replacement for the token column to avoid storing email
tokens in plaintext as it can pose a security risk. The new scope column
ensures that email tokens cannot be used to perform a different action
than the one intended.
To sum up, this commit:
* Adds token_hash and scope to email_tokens
* Reuses code that schedules critical_user_email
* Refactors EmailToken.confirm and EmailToken.atomic_confirm methods
* Periodically cleans old, unconfirmed or expired email tokens
Administrators can use second factor to confirm granting admin access
without using email. The old method of confirmation via email is still
used as a fallback when second factor is unavailable.
* FIX: Revoking admin or moderator status doesn't require refresh to delete/anonymize/merge user
On the /admin/users/<id>/<username> page, there are action buttons that are either visible or hidden depending on a few fields from the AdminDetailsSerializer: `can_be_deleted`, `can_be_anonymized`, `can_be_merged`, `can_delete_all_posts`.
These fields are updated when granting/revoking admin or moderator status. However, those updates were not being reflected on the page. E.g. if a user is granted moderation privileges, the 'anonymize user' and 'merge' buttons still appear on the page, which is inconsistent with the backend state of the user. It requires refreshing the page to update the state.
This commit fixes that issue, by syncing the client model state with the server state when handling a successful response from the server. Now, when revoking privileges, the buttons automatically appear without refreshing the page. Similarly, when granting moderator privileges, the buttons automatically disappear without refreshing the page.
* Add detailed user response to spec for changed routes.
Add tests to verify that the revoke_moderation, grant_moderation, and revoke_admin routes return a response formatted according to the AdminDetailedUserSerializer.
We shouldn't be checking if a user is allowed to do an action in the logger. We should be checking it just before we perform the action. In fact, guardians in the logger can make things even worse in case of a security bug. Let's say we forgot to check user's permissions before performing some action, but we still have a call to the guardian in the logger. In this case, a user would perform the action anyway, and this action wouldn't even be logged!
I've checked all cases and I confirm that we're safe to delete this calls from the logger.
I've added two calls to guardians in admin/user_controller. We didn't have security bugs there, because regular users can't access admin/... routes at all. But it's good to have calls to guardian in these methods anyway, neighboring methods have them.
scopes are incredibly annoying to preload, simply adding :user_emails is not
enough.
Instead of relying on scopes simply iterate through user_emails which is
properly preloaded.
This removes 2 * N+1 when generating user reports.
This makes behavior consistent with documentation:
API:
> Will send an email with this message when present
Web UI:
> Optionally, provide more information about the suspension and it will be emailed to the user
We were sending 2 emails for user silencing if a message was provided in the UI. Also always send email for user silence and user suspend with reason regardless of whether message provided.
The 'Discourse SSO' protocol is being rebranded to DiscourseConnect. This should help to reduce confusion when 'SSO' is used in the generic sense.
This commit aims to:
- Rename `sso_` site settings. DiscourseConnect specific ones are prefixed `discourse_connect_`. Generic settings are prefixed `auth_`
- Add (server-side-only) backwards compatibility for the old setting names, with deprecation notices
- Copy `site_settings` database records to the new names
- Rename relevant translation keys
- Update relevant translations
This commit does **not** aim to:
- Rename any Ruby classes or methods. This might be done in a future commit
- Change any URLs. This would break existing integrations
- Make any changes to the protocol. This would break existing integrations
- Change any functionality. Further normalization across DiscourseConnect and other auth methods will be done separately
The risks are:
- There is no backwards compatibility for site settings on the client-side. Accessing auth-related site settings in Javascript is fairly rare, and an error on the client side would not be security-critical.
- If a plugin is monkey-patching parts of the auth process, changes to locale keys could cause broken error messages. This should also be unlikely. The old site setting names remain functional, so security-related overrides will remain working.
A follow-up commit will be made with a post-deploy migration to delete the old `site_settings` rows.
Users could be silenced or suspended by two staff members at the same time and
would not be aware of it. This commit shows an error message if another penalty
has been applied.
These fields are required when using the UI and if `suspend_until`
params isn't used the user never is actually suspended so we should
require these fields when suspending a user.
