This commit moves some code out of UploadController#show_secure
so it can be reused in other controllers if a secure upload
needs to have permission checks run.
Why this change?
This commit updates `ThemeSettingsObjectValidator` to validate a
property's value against the validations listed in the schema.
For string types, `min_length`, `max_length` and `url` are supported.
For integer and float types, `min` and `max` are supported.
Why this change?
This change adds property value validation to `ThemeSettingsObjectValidator`
for the following types: "string", "integer", "float", "boolean", "enum". Note
that this class is not being used anywhere yet and is still in
development.
This data is cached, so we don't want to include any site-specific-logic in there. Let's just keep the old URL-collecting behaviour, and let it be stripped out by `CSP::Builder` at runtime.
The strict-dynamic CSP directive is supported in all our target browsers, and makes for a much simpler configuration. Instead of allowlisting paths, we use a per-request nonce to authorize `<script>` tags, and then those scripts are allowed to load additional scripts (or add additional inline scripts) without restriction.
This becomes especially useful when admins want to add external scripts like Google Tag Manager, or advertising scripts, which then go on to load a ton of other scripts.
All script tags introduced via themes will automatically have the nonce attribute applied, so it should be zero-effort for theme developers. Plugins *may* need some changes if they are inserting their own script tags.
This commit introduces a strict-dynamic-based CSP behind an experimental `content_security_policy_strict_dynamic` site setting.

It's complicated...we have multiple "anonymous" user concepts
in core, and even two classes called the exact same thing --
AnonymousUser.
The first case is Guardian::AnonymousUser, which is used for
people who are browsing the forum without being authenticated.
The second case is the model AnonymousUser, which is used when
a user is liking or posting anonymously via allow_anonymous_likes
or allow_anonymous_posting site settings.
We will untangle this naming nightmare later on...but for the
time being, only authenticated users who are pretending to be
anonymous should be able to like posts if allow_anonymous_likes
is on.

This is a first pass at adding an objects validator which main's job is
to validate an object against a defined schema which we will support. In
this pass, we are simply validating that properties that has been marked
as required are present in the object.
The `-ping` option significantly speeds up the ImageMagick `identify` command per our testing and the [documentation](https://imagemagick.org/script/command-line-options.php#ping):
> -ping
Efficiently determine these image characteristics: image number, the file name, the width and height of the image, whether the image is colormapped or not, the number of colors in the image, the number of bytes in the image, the format of the image (JPEG, PNM, etc.). Use +ping to ensure accurate image properties.
We already pass the `-ping` option in other places where the `identify` command is used, so it makes sense to use the option everywhere.

Why this change?
On CI, we have been seeing flaky system tests because ActiveRecord is
unable to checkout a connection. This patch is meant to help us debug
which thread is not returning the connection to the queue.
Fixes an issue where private topics that are quoted have an incorrectly formatted url when using a subfolder install.
This update returns a relative url that includes the base_path rather than a combination of base_url + base_path.
This commit changes `max_image_megapixels` to be used
as is without multiplying by 2 to give extra leway.
We found in reality this was just causing confusion
for admins, especially with the already permissive
40MP default.
This reverts commit 767b49232e.
If anything else (e.g. GTM integration) introduces a nonce/hash, then this change stops the splash screen JS to fail and makes sites unusable.
Removes duplication from LimitedEdit to see who can edit
posts, and also removes the old trust level setting check
since it's no longer necessary.
Also make it so staff can always edit since can_edit_post?
already has a staff escape hatch.
Why this change?
This commit introduces an experimental `type: objects` theme setting
which will allow theme developers to store a collection of objects as
JSON in the database. Currently, the feature is still in development and
this commit is simply setting up the ground work for us to introduce the
feature in smaller pieces.
What does this change do?
1. Adds a `json_value` column as `jsonb` data type to the `theme_settings` table.
2. Adds a `experimental_objects_type_for_theme_settings` site setting to
determine whether `ThemeSetting` records of with the `objects` data
type can be created.
3. Updates `ThemeSettingsManager` to support read/write access from the
`ThemeSettings#json_value` column.

post_links_allowed_groups is an odd check tied to
unrestricted_link_posting? in PostGuardian, in that
it doesn't have an escape hatch for staff like most
of the rest of these group based settings.
It doesn't make sense to exclude admins or mods from
posting links, so just always allow them to avoid confusion.
Browsers will ignore unsafe-inline if nonces or hashes are included in the CSP. When unsafe-inline is enabled, nonces and hashes are not required, so we can skip them.
Our strong recommendation remains that unsafe-inline should not be used in production.
We've changed access settings to be group membership based rather than based on the TL value directly. We kept both conditions here while we updated any plugins and themes. It should now be safe to remove.
JS assets added by plugins via `register_asset` will be outside the `assets/javascripts` directory, and are therefore exempt from being transpiled. That means that there isn't really any need to run them through DiscourseJsProcessor. Instead, we can just concatenate them together, and avoid the need for all the sprockets-wrangling.
This commit also takes the opportunity to clean up a number of plugin-asset-related codepaths which are no longer required (e.g. globs, handlebars)
Why this change?
Since 1dba1aca27, we have been remapping
the `<->` proximity operator in a tsquery to `&`. However, there is
another variant of it which follows the `<N>` pattern. For example, the
following text "end-to-end" will eventually result in the following
tsquery `end-to-end:* <-> end:* <2> end:*` being generated by Postgres.
Before this fix, the tsquery is remapped to `end-to-end:* & end:* <2>
end:*` by us. This is requires the search data which we store to contain
`end` at exactly 2 position apart. Due to the way we limit the
number of duplicates in our search data, the search term may end up not
matching anything. In bd32912c5e, we made
it such that we do not allow any duplicates when indexing a topic's
title. Therefore, search for `end-to-end` against a topic title with
`end-to-end` will never match because our index will only contain one
`end` term.
What does this change do?
We will remap the `<N>` variant of the proximity operator.
We were having a minor issue with emails with embedded images
that had newlines in the alt string; for example:
```
<p class="MsoNormal"><span style="font-size:11.0pt"><img width="898"
height="498" style="width:9.3541in;height:5.1875in" id="Picture_x0020_5"
src="cid:image003.png@01DA4EBA.0400B610" alt="A screenshot of a computer
program
Description automatically generated"></span><span
style="font-size:11.0pt"><o:p></o:p></span></p>
```
Once this was parsed and converted to markdown (or directly to HTML
in some cases), this caused an issue in the composer and the post
UI, where the markdown parser didn't know how to deal with this,
making the HTML show directly instead of showing an image.
The easiest way to deal with this is to just strip \n from image
alt and title attrs in the HTMLToMarkdown class.
These routes were previously rendered using Rails, and had a fairly fragile 2fa implementation in vanilla-js. This commit refactors the routes to be handled in the Ember app, removes the custom vanilla-js bundles, and leans on our centralized 2fa implementation. It also introduces a set of system specs for the behavior.
Safari has a bug which means that scripts with the `defer` attribute are executed before stylesheets have finished loading. This is being tracked at https://bugs.webkit.org/show_bug.cgi?id=209261.
This commit works around the problem by introducing a no-op inline `<script>` to the end of our HTML document. This works because defer scripts are guaranteed to run after inline scripts, and inline scripts are guaranteed to run after any preceding stylesheets.
Technically we only need this for Safari. But given that the cost is so low, it makes sense to include it everywhere rather than incurring the complexity of gating it by user-agent.
In a handful of situations, we need to verify a user's 2fa credentials before `current_user` is assigned. For example: login, email_login and change-email confirmation. This commit adds an explicit `target_user:` parameter to the centralized 2fa system so that it can be used for those situations.
For safety and clarity, this new parameter only works for anon. If some user is logged in, and target_user is set to a different user, an exception will be raised.
We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_level_to_tag_topics site setting to tag_topic_allowed_groups.
Previously, it was not possible to modify the sorting order of the `TopicQuery` result from a plugin. This feature adds support to specify custom sorting functionality in a plugin. We're using the `apply_modifier` method in the `DiscoursePluginRegistry` module to achieve it.
