When redirecting to login, we store a destination_url cookie, which the user is then redirected to after login. We never want the user to be redirected to a JSON URL. Instead, we should return a 403 in these situations.
This should also be much less confusing for API consumers - a 403 is a better representation than a 302.

`auto_update` is true by default at the database level, but it doesn't make sense for `auto_update` to be true on themes that are not imported from a Git repository.
Under some conditions, these varied responses could lead to cache poisoning, hence the 'security' label.
Previously the Rails application would serve JSON data in place of HTML whenever Ember CLI requested an `application.html.erb`-rendered page. This commit removes that logic, and instead parses the HTML out of the standard response. This means that Rails doesn't need to customize its response for Ember CLI.
* DEV: Specify bookmarks order
It's better to order by id than to have a semi-random order. Fixes a flaky test:
```
1) TopicView with a few sample posts #bookmarks gets the first post bookmark reminder at for the user
59
Failure/Error: expect(first[:post_id]).to eq(bookmark1.post_id)
60
61
expected: 1901
62
got: 1902

* Change test
* Revert "DEV: Specify bookmarks order"
This reverts commit 1f50026231.
* REFACTOR: Improve support for consolidating notifications.
Before this commit, we didn't have a single way of consolidating notifications. For notifications like group summaries, we manually removed old ones before creating a new one. On the other hand, we used an after_create callback for likes and group membership requests, which caused unnecessary work, as we need to delete the record we created to replace it with a consolidated one.
We now have all the consolidation rules centralized in a single place: the consolidation planner class. Other parts of the app looking to create a consolidable notification can do so by calling Notification#consolidate_or_save!, instead of the default Notification#create! method.
Finally, we added two more rules: one for re-using existing group summaries and another for deleting duplicated dashboard problems PMs notifications when the user is tracking the moderator's inbox. Setting the threshold to one forces the planner to apply this rule every time.
I plan to add plugin support for adding custom rules in another PR to keep this one relatively small.
* DEV: Introduces a plugin API for consolidating notifications.
This commit removes the `Notification#filter_by_consolidation_data` scope since plugins could have to define their criteria. The Plan class now receives two blocks, one to query for an already consolidated notification, which we'll try to update, and another to query for existing ones to consolidate.
It also receives a consolidation window, which accepts an ActiveSupport::Duration object, and filter notifications created since that value.
Recently, the wrong new behavior appeared – we started to suggest to invited users usernames like "user1".
To reproduce:
1. Create an invitation with default settings, do not restrict it to email
2. Copy an invitation link and follow it in incognito mode
See username already filled, with eg “user1”. See screenshot. Should be empty.
This bug was very likely introduced by my recent changes to UserNameSuggester.
We have a couple of site setting, `slow_down_crawler_user_agents` and `slow_down_crawler_rate`, that are meant to allow site owners to signal to specific crawlers that they're crawling the site too aggressively and that they should slow down.
When a crawler is added to the `slow_down_crawler_user_agents` setting, Discourse currently adds a `Crawl-delay` directive for that crawler in `/robots.txt`. Unfortunately, many crawlers don't support the `Crawl-delay` directive in `/robots.txt` which leaves the site owners no options if a crawler is crawling the site too aggressively.
This PR replaces the `Crawl-delay` directive with proper rate limiting for crawlers added to the `slow_down_crawler_user_agents` list. On every request made by a non-logged in user, Discourse will check the User Agent string and if it contains one of the values of the `slow_down_crawler_user_agents` list, Discourse will only allow 1 request every N seconds for that User Agent (N is the value of the `slow_down_crawler_rate` setting) and the rest of requests made within the same interval will get a 429 response.
The `slow_down_crawler_user_agents` setting becomes quite dangerous with this PR since it could rate limit lots if not all of anonymous traffic if the setting is not used appropriately. So to protect against this scenario, we've added a couple of new validations to the setting when it's changed:
1) each value added to setting must 3 characters or longer
2) each value cannot be a substring of tokens found in popular browser User Agent. The current list of prohibited values is: apple, windows, linux, ubuntu, gecko, firefox, chrome, safari, applewebkit, webkit, mozilla, macintosh, khtml, intel, osx, os x, iphone, ipad and mac.
Currently when a user creates posts that are moderated (for whatever
reason), a popup is displayed saying the post needs approval and the
total number of the user’s pending posts. But then this piece of
information is kind of lost and there is nowhere for the user to know
what are their pending posts or how many there are.
This patch solves this issue by adding a new “Pending” section to the
user’s activity page when there are some pending posts to display. When
there are none, then the “Pending” section isn’t displayed at all.

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
When this setting is turned on, it will check that normalized emails
are unique. Normalized emails are emails without any dots or plus
aliases.
This setting can be used to block use of aliases of the same email
address.
Use @here to mention all users that were allowed to topic directly or
through group, who liked topics or read the topic. Only first 10 users
will be notified.
Allow current user to keep existent tags when adding or removing a tag.
For example, a user could not remove a tag from a topic if the topic
had another tag that was restricted to a different category.
The users all shared the same `User#last_seen_at` column so depending on
how the database returned the records, the user that we're interested in
may be excluded from the update query.
Follow-up to 8226ab1099
In b8c8909a9d, we introduced a regression
where users may have had their `UserStat.first_unread_pm_at` set
incorrectly. This commit introduces a migration to reset `UserStat.first_unread_pm_at` back to
`User#created_at`.
Follow-up to b8c8909a9d.
Similar to site settings, adds support for `refresh` option to theme settings.
```yaml
super_feature_enabled:
type: bool
default: false
refresh: true
```
We are pushing /notification-alert/#{user_id} and /notification/#{user_id}
messages to MessageBus from both PostAlerter and User#publish_notification_state.
This can cause memory issues on large sites with many users. This commit
stems the bleeding by only sending these alert messages if the user
in question has been seen in the last 30 days, which eliminates a large
chunk of users on some sites.
When rendering the markdown code blocks we replace the
offending characters in the output string with spans highlighting a textual
representation of the character, along with a title attribute with
information about why the character was highlighted.
The list of characters stripped by this fix, which are the bidirectional
characters considered relevant, are:
U+202A
U+202B
U+202C
U+202D
U+202E
U+2066
U+2067
U+2068
U+2069
Previously, incorrect reply counts are displayed in the "top categories" section of the user summary page since we included the `moderator_action` and `small_action` post types.

This commit refactors the direct external upload routes (get presigned
put, complete external, create/abort/complete multipart) into a
helper which is then included in both BackupController and the
UploadController. This is done so UploadController doesn't need
strange backup logic added to it, and so each controller implementing
this helper can do their own validation/error handling nicely.
This is a follow up to e4350bb966
Currently, Discourse rate limits all incoming requests by the IP address they
originate from regardless of the user making the request. This can be
frustrating if there are multiple users using Discourse simultaneously while
sharing the same IP address (e.g. employees in an office).
This commit implements a new feature to make Discourse apply rate limits by
user id rather than IP address for users at or higher than the configured trust
level (1 is the default).
For example, let's say a Discourse instance is configured to allow 200 requests
per minute per IP address, and we have 10 users at trust level 4 using
Discourse simultaneously from the same IP address. Before this feature, the 10
users could only make a total of 200 requests per minute before they got rate
limited. But with the new feature, each user is allowed to make 200 requests
per minute because the rate limits are applied on user id rather than the IP
address.
The minimum trust level for applying user-id-based rate limits can be
configured by the `skip_per_ip_rate_limit_trust_level` global setting. The
default is 1, but it can be changed by either adding the
`DISCOURSE_SKIP_PER_IP_RATE_LIMIT_TRUST_LEVEL` environment variable with the
desired value to your `app.yml`, or changing the setting's value in the
`discourse.conf` file.
Requests made with API keys are still rate limited by IP address and the
relevant global settings that control API keys rate limits.
Before this commit, Discourse's auth cookie (`_t`) was simply a 32 characters
string that Discourse used to lookup the current user from the database and the
cookie contained no additional information about the user. However, we had to
change the cookie content in this commit so we could identify the user from the
cookie without making a database query before the rate limits logic and avoid
introducing a bottleneck on busy sites.
Besides the 32 characters auth token, the cookie now includes the user id,
trust level and the cookie's generation date, and we encrypt/sign the cookie to
prevent tampering.

When 31035010af
was done it failed to take into account the case where the smtp_enabled
site setting was true, but the topic had no allowed groups / no
incoming email record, which caused errors for topics even with
nothing to do with group SMTP.
Uppy adds the file name as the "name" parameter in the
payload by default, which means that for things like the
emoji uploader which have a name param used by the controller,
that param will be passed as the file name. We already use
the existing file name if the name param is null, so this
commit just does further cleanup of the name param, removing
the extension if it is a filename so we don't end up with
emoji names like blah_png.
When there are multiple groups on a topic, we were selecting
the first from the topic allowed groups to act as the sender
email address when sending group SMTP replies via PostAlerter.
However, this was not ordered, and since there is no created_at
column on TopicAllowedGroup we cannot order this nicely, which
caused just a random group to be used (based on whatever postgres
decided it felt like that morning).
This commit changes the group used for SMTP sending to be the
group using the email_username of the to address of the first
incoming email for the topic, if there are more than one allowed
groups on the topic. Otherwise it just uses the only SMTP enabled
group.
Sometimes, a user may have a malformed email such as
`test@test.com<mailto:test@test.com` their email address,
and as a topic participant will be included as a CC email
when sending a GroupSmtpEmail. This causes the CC parsing to
fail and further down the line in Email::Sender the code
to check the CC addresses expects an array but gets a string
instead because of the parse failure.
Instead, we can just check if the CC addresses are valid
and drop them if they are not in the GroupSmtpEmail job.
This only affects multisite Discourse instances (where multiple forums are served from a single application server). The vast majority of self-hosted Discourse forums do not fall into this category.
On affected instances, this vulnerability could allow encrypted session cookies to be re-used between sites served by the same application instance.
Uppy and Resumable slice up their chunks differently, which causes a difference
in this algorithm. Let's take a 131.6MB file (137951695 bytes) with a 5MB (5242880 bytes)
chunk size. For resumable, there are 26 chunks, and uppy there are 27. This is
controlled by forceChunkSize in resumable which is false by default. The final
chunk size is 6879695 (chunk size + remainder) whereas in uppy it is 1636815 (just remainder).
This means that the current condition of uploaded_file_size + current_chunk_size >= total_size
is hit twice by uppy, because it uses a more correct number of chunks. This
can be solved for both uppy and resumable by checking the _previous_ chunk
number * chunk_size as the uploaded_file_size.
An example of what is happening before that change, using the current
chunk number to calculate uploaded_file_size.
chunk 26: resumable: uploaded_file_size (26 * 5242880) + current_chunk_size (6879695) = 143194575 >= total_size (137951695) ? YES
chunk 26: uppy: uploaded_file_size (26 * 5242880) + current_chunk_size (5242880) = 141557760 >= total_size (137951695) ? YES
chunk 27: uppy: uploaded_file_size (27 * 5242880) + current_chunk_size (1636815) = 143194575 >= total_size (137951695) ? YES
An example of what this looks like after the change, using the previous
chunk number to calculate uploaded_file_size:
chunk 26: resumable: uploaded_file_size (25 * 5242880) + current_chunk_size (6879695) = 137951695 >= total_size (137951695) ? YES
chunk 26: uppy: uploaded_file_size (25 * 5242880) + current_chunk_size (5242880) = 136314880 >= total_size (137951695) ? NO
chunk 27: uppy: uploaded_file_size (26 * 5242880) + current_chunk_size (1636815) = 137951695 >= total_size (137951695) ? YES
Same issue as 28b00dc6fc, the
Mocha::ExpectationError inherits from Exception instead
of StandardError so RspecErrorTracker does not show the
actual failed expectation in request specs, the status of
the response is just 500 with no further detail.
This commit adds the RailsMultisite middleware in test mode when Rails.configuration.multisite is true. This allows for much more realistic integration testing. The `multisite_spec.rb` file is rewritten to avoid needing to simulate a middleware stack.
