We've seen in some communities abuse of user profile where bios and other fields are used in malicious ways, such as malware distribution. A common pattern between all the abuse cases we've seen is that the malicious actors tend to have 0 posts and have a low trust level.
To eliminate this abuse vector, or at least make it much less effective, we're making the following changes to user profiles:
1. Anonymous, TL0 and TL1 users cannot see any user profiles for users with 0 posts except for staff users
2. Anonymous and TL0 users can only see profiles of TL1 users and above
Users can always see their own profile, and they can still hide their profiles via the "Hide my public profile" preference. Staff can always see any user's profile.
Internal topic: t/142853.
As part of a previous fix we changed which groups are serialized for a user, in order to fix a bug in the default group selector under user preferences.
However, we should only change this when serializing the current user. This change combines the old code-path and the new based on who is serializing.
The user serializer groups method previously relied on the members_visible_groups to determine groups that the user should be able to see, however this setting was intended for visibility of group members (which is entirely different).
The result of this could be seen when choosing a primary group from user preferences -> account, due to the serializer the group name was not visible when members_visible_groups was set to owners.
The most common thing that we do with fab! is:
fab!(:thing) { Fabricate(:thing) }
This commit adds a shorthand for this which is just simply:
fab!(:thing)
i.e. If you omit the block, then, by default, you'll get a `Fabricate`d object using the fabricator of the same name.
Adds UI elements for registering a passkey and logging in with it. The feature is still in an early stage, interested parties that want to try it can use the `experimental_passkeys` site setting (via Rails console).

This is part 2 (of 3) for passkeys support.
This adds a hidden site setting plus routes and controller actions.
1. registering passkeys
Passkeys are registered in a two-step process. First, `create_passkey`
returns details for the browser to create a passkey. This includes
- a challenge
- the relying party ID and Origin
- the user's secure identifier
- the supported algorithms
- the user's existing passkeys (if any)
Then the browser creates a key with this information, and submits it to
the server via `register_passkey`.
2. authenticating passkeys
A similar process happens here as well. First, a challenge is created
and sent to the browser. Then the browser makes a public key credential
and submits it to the server via `passkey_auth_perform`.
3. renaming/deleting passkeys
These routes allow changing the name of a key and deleting it.
4. checking if session is trusted for sensitive actions
Since a passkey is a password replacement, we want to make sure to confirm the user's identity before allowing adding/deleting passkeys. The u/trusted-session GET route returns success if user has confirmed their session (and failed if user hasn't). In the frontend (in the next PR), we're using these routes to show the password confirmation screen.
The `/u/confirm-session` route allows the user to confirm their session with a password. The latter route's functionality already existed in core, under the 2FA flow, but it has been abstracted into its own here so it can be used independently.

This PR splits up the preference that controls the count vs dot and destination of sidebar links, which is really hard to understand, into 2 simpler checkboxes:
The new preferences/checkboxes are off by default, but there are database migrations to switch the old preference to the new ones so that existing users don't have to update their preferences to keep their preferred behavior of sidebar links when this changed is rolled out.
Internal topic: t/103529.
This new site setting replaces the
`enable_experimental_sidebar_hamburger` and `enable_sidebar` site
settings as the sidebar feature exits the experimental phase.
Note that we're replacing this without depreciation since the previous
site setting was considered experimental.
Internal Ref: /t/86563
In this PR, we introduced an option, that when all authenticators are disabled, but backup codes still exists, user can authenticate with those backup codes. This was reverted as this is not expected behavior.
https://github.com/discourse/discourse/pull/18982
Instead, when the last authenticator is deleted, backup codes should be deleted as well. Because this disables 2fa, user is asked to confirm that action by typing text.
In addition, UI for 2fa preferences was refreshed.
Currently, we have available three 2fa methods:
- Token-Based Authenticators
- Physical Security Keys
- Two-Factor Backup Codes
If the first two are deleted, user lose visibility of their backup codes, which suggests that 2fa is disabled.
However, when they try to authenticate, the account is locked, and they have to ask admin to fix that problem.
This PR is fixing the issue. User still sees backup codes in their panel and can use them to authenticate.
In next PR, I will improve UI to clearly notify the user when 2fa is fully disabled and when it is still active.
Before, `sidebar_list_destination` was an attribute on UserOptionSerializer. The problem was that this attribute was added to user model only when the user entered the preferences panel. We want that attribute to be available all the time, therefore it was moved to CurrentUserSerializer.
Previously, PM only tags were being routed to the public topic list with
the tag added as a filter. However, the public topic list does not fetch
PMs and hence PM only tags did not provide any value when added to the
Sidebar. This commit changes that by allowing the client to
differentiate PM only tag and thus routes the link to the PM tags show
route.
Counts for PM only tags section links are not supported as of this
commit and will be added in a follow up commit.
It's very easy to forget to add `require 'rails_helper'` at the top of every core/plugin spec file, and omissions can cause some very confusing/sporadic errors.
By setting this flag in `.rspec`, we can remove the need for `require 'rails_helper'` entirely.
This is a recent regression introduced by https://github.com/discourse/discourse/pull/12937 which makes it so that when looking at a user profile that is not your own, specifically the category and tag notification settings, you would see your own settings instead of the target user. This is only a problem for admins because regular users cannot see these details for other users.
The issue was that we were using `scope` in the serializer, which refers to the current user, rather than using a scope for the target user via `Guardian.new(user)`.
However, on further inspection the `notification_levels_for` method for `TagUser` and `CategoryUser` did not actually need to be accepting an instance of Guardian, all that it was using it for was to check guardian.anonymous? which is just a fancy way of saying user.blank?. Changed this method to just accept a user instead and send the user in from the serializer.
Moderators should not be able to see `UserSerializer#group_users` and `UserSerializer#second_factor_enabled` of other users.
Impact of leaking this is low because the information leaked is not
exploitable.
* DEV: Add framework for filtered plugin registers
Plugins often need to add values to a list, and we need to filter those lists at runtime to ignore values from disabled plugins. This commit provides a re-usable way to do that, which should make it easier to add new registers in future, and also reduce repeated code.
Follow-up commits will migrate existing registers to use this new system
* DEV: Migrate user and group custom field APIs to plugin registry
This gives us a consistent system for checking plugin enabled state, so we are repeating less logic. API changes are backwards compatible
* If a staff user created only a security key as their single 2FA option. they continued to be prompted to create a 2FA option because we only considered this condition satisfied if a TOTP was added.
* The condition is now satisfied if TOTP OR security keys are enabled.
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
This reverts commit 1fbe078ae0.
`UserProfile` is created in a callback after the user has been created.
As such, it should be impossible for a user to not have a blank
`UserProfile`. This was also improved in
4f5c9bb8d3.
Apparently is is possible to have a user without a user_profile. This
fix will return nil for any user_profile fields during serialization
(like the after delete web hook) instead of blowing up.
* Introduced fab!, a helper that creates database state for a group
It's almost identical to let_it_be, except:
1. It creates a new object for each test by default,
2. You can disable it using PREFABRICATION=0
`Upload#url` is more likely and can change from time to time. When it
does changes, we don't want to have to look through multiple tables to
ensure that the URLs are all up to date. Instead, we simply associate
uploads properly to `UserProfile` so that it does not have to replicate
the URLs in the table.
This change both speeds up specs (less strings to allocate) and helps catch
cases where methods in Discourse are mutating inputs.
Overall we will be migrating everything to use #frozen_string_literal: true
it will take a while, but this is the first and safest move in this direction
Users can no longer opt-in for "public" edit history
if site owner disables it.
This feature adds cost and complexity to post rendering since
user options need to be premeptively loaded for every user in the
stream. It is also confusing to explain to communities with private edit
history.
