Mathieu FenniakandMathieu Fenniak f93d2cb261 ci: detect and prevent empty case statements in Go code (#11593)
One of the security patches released 2026-03-09 [fixed a vulnerability](https://codeberg.org/forgejo/forgejo/pulls/11513/commits/d1c7b04d09f6a13896eaa1322ac690b2021539da) caused by a misapplication of Go `case` statements, where the implementation would have been correct if Go `case` statements automatically fall through to the next case block, but they do not.  This PR adds a semgrep rule which detects any empty `case` statement and raises an error, in order to prevent this coding mistake in the future.

For example, code like this will now trigger a build error:
```go
	switch setting.Protocol {
	case setting.HTTPUnix:
	case setting.FCGI:
	case setting.FCGIUnix:
	default:
		defaultLocalURL := string(setting.Protocol) + "://"
	}
```

Example error:
```
    cmd/web.go
   ❯❯❱ semgrep.config.forgejo-switch-empty-case
          switch has a case block with no content. This is treated as "break" by Go, but developers may
          confuse it for "fallthrough".  To fix this error, disambiguate by using "break" or
          "fallthrough".

          279┆ switch setting.Protocol {
          280┆ case setting.HTTPUnix:
          281┆ case setting.FCGI:
          282┆ case setting.FCGIUnix:
          283┆ default:
          284┆   defaultLocalURL := string(setting.Protocol) + "://"
          285┆   if setting.HTTPAddr == "0.0.0.0" {
          286┆           defaultLocalURL += "localhost"
          287┆   } else {
          288┆           defaultLocalURL += setting.HTTPAddr
```

As described in the error output, this error can be fixed by explicitly listing `break` (the real Go behaviour, to do nothing in the block), or by listing `fallthrough` (if the intent was to fall through).

All existing code triggering this detection has been changed to `break` (or, rarely, irrelevant cases have been removed), which should maintain the same code functionality.  While performing this fixup, a light analysis was performed on each case and they *appeared* correct, but with ~65 cases I haven't gone into extreme depth.

Tests are present for the semgrep rule in `.semgrep/tests/go.go`.

Oliver EikemeierandGusted d499c3b132 chore: rename AccessTokenError to AccessTokenErrorResponse (#11595)
AccessTokenError is never used as a Go error. In fact, it is returned
as a *AccessTokenError (which would result in a `nil` error when cast).

Rename the struct to a more accurate name and remove the unused
`Error() string` method to prevent future confusion.

GustedandMathieu Fenniak d1c7b04d09 fix: verify code challenge of S256
We do not know for sure, but it is quite likely someone assumed implicit
fallthrough. This meant that if someone used S256 for PKCE, it simply
did not verify the code challenge and always accepted it.

GustedandEarl Warren 7f8f9b878f fix: Revert "allow synchronizing user status from OAuth2 login providers (#31572)"
This commit has a fundamental flaw, in order to syncronize if external
users are still active the commit checks if the refresh token is
accepted by the OAuth provider, if that is not the case it sees that as
the user is disabled and sets the is active field to `false` to signal
that. Because it might be possible (this commit makes this a highly
likelyhood) that the OAuth provider still recognizes this user the
commit introduces code to allow users to re-active themselves via the
oauth flow if they were disabled because of this. However this code
makes no distinction in why the user was disabled and always re-actives
the user.

Thus the reactivation via the OAuth flow allows users to bypass the
manually activation setting (`[service].REGISTER_MANUAL_CONFIRM`) or if
the admin for other reasons disabled the user.

This reverts commit 21fdd28f08.

Cherry-pick of [gitea#32542](https://github.com/go-gitea/gitea/pull/32542).

This makes /login/oauth/authorize behave the same way as the /login/oauth/userinfo endpoint. Previously, `name` property of the returned OIDCToken used to depend on the UI.DefaultShowFullName setting (I don't think this is desired behavior). Even worse, the `userinfo` endpoint can return basically the same data, but the `name` value there always returned `FullName`, even if it's empty (no fallback to `Name`).

A few notes:

I'm not sure what branch to target with this PR, please correct me if I'm chose the wrong one.

The deleted lines in the tests are duplicates, there's a copy of the whole thing just below, the only difference being the `Name` field (used to test the dependency on the UI.DefaultShowFullName setting)

Rowan BohdeandGergely Nagy 21fdd28f08 allow synchronizing user status from OAuth2 login providers (#31572)
This leverages the existing `sync_external_users` cron job to
synchronize the `IsActive` flag on users who use an OAuth2 provider set
to synchronize. This synchronization is done by checking for expired
access tokens, and using the stored refresh token to request a new
access token. If the response back from the OAuth2 provider is the
`invalid_grant` error code, the user is marked as inactive. However, the
user is able to reactivate their account by logging in the web browser
through their OAuth2 flow.

Also changed to support this is that a linked `ExternalLoginUser` is
always created upon a login or signup via OAuth2.

Ideally, we would also refresh permissions from the configured OAuth
provider (e.g., admin, restricted and group mappings) to match the
implementation of LDAP. However, the OAuth library used for this `goth`,
doesn't seem to support issuing a session via refresh tokens. The
interface provides a [`RefreshToken`
method](https://github.com/markbates/goth/blob/master/provider.go#L20),
but the returned `oauth.Token` doesn't implement the `goth.Session` we
would need to call `FetchUser`. Due to specific implementations, we
would need to build a compatibility function for every provider, since
they cast to concrete types (e.g.
[Azure](https://github.com/markbates/goth/blob/master/providers/azureadv2/azureadv2.go#L132))

Zettat123andEarl Warren 886a675f62 Return access_denied error when an OAuth2 request is denied (#30974)
According to [RFC
6749](https://datatracker.ietf.org/doc/html/rfc6749#section-4.1.2.1),
when the resource owner or authorization server denied an request, an
`access_denied` error should be returned. But currently in this case
Gitea does not return any error.

For example, if the user clicks "Cancel" here, an `access_denied` error
should be returned.

ArcherandEarl Warren 1b088fade6 Prevent automatic OAuth grants for public clients (#30790)
This commit forces the resource owner (user) to always approve OAuth 2.0
authorization requests if the client is public (e.g. native
applications).

As detailed in [RFC 6749 Section 10.2](https://www.rfc-editor.org/rfc/rfc6749.html#section-10.2),

> The authorization server SHOULD NOT process repeated authorization
requests automatically (without active resource owner interaction)
without authenticating the client or relying on other measures to ensure
that the repeated request comes from the original client and not an
impersonator.

With the implementation prior to this patch, attackers with access to
the redirect URI (e.g., the loopback interface for
`git-credential-oauth`) can get access to the user account without any
user interaction if they can redirect the user to the
`/login/oauth/authorize` endpoint somehow (e.g., with `xdg-open` on
Linux).

Fixes #25061.

Earl Warren 7cabc5670d Implement remote user login source and promotion to regular user
A remote user (UserTypeRemoteUser) is a placeholder that can be
promoted to a regular user (UserTypeIndividual). It represents users
that exist somewhere else. Although the UserTypeRemoteUser already
exists in Forgejo, it is neither used or documented.

A new login type / source (Remote) is introduced and set to be the login type
of remote users.

Type        UserTypeRemoteUser
LogingType  Remote

The association between a remote user and its counterpart in another
environment (for instance another forge) is via the OAuth2 login
source:

LoginName   set to the unique identifier relative to the login source
LoginSource set to the identifier of the remote source

For instance when migrating from GitLab.com, a user can be created as
if it was authenticated using GitLab.com as an OAuth2 authentication
source.

When a user authenticates to Forejo from the same authentication
source and the identifier match, the remote user is promoted to a
regular user. For instance if 43 is the ID of the GitLab.com OAuth2
login source, 88 is the ID of the Remote loging source, and 48323
is the identifier of the foo user:

Type        UserTypeRemoteUser
LogingType  Remote
LoginName   48323
LoginSource 88
Email       (empty)
Name        foo

Will be promoted to the following when the user foo authenticates to
the Forgejo instance using GitLab.com as an OAuth2 provider. All users
with a LoginType of Remote and a LoginName of 48323 are examined. If
the LoginSource has a provider name that matches the provider name of
GitLab.com (usually just "gitlab"), it is a match and can be promoted.

The email is obtained via the OAuth2 provider and the user set to:

Type        UserTypeIndividual
LogingType  OAuth2
LoginName   48323
LoginSource 43
Email       foo@example.com
Name        foo

Note: the Remote login source is an indirection to the actual login
source, i.e. the provider string my be set to a login source that does
not exist yet.

Lunny XiaoandEarl Warren 894d9b2836 Move context from modules to services (#29440)
Since `modules/context` has to depend on `models` and many other
packages, it should be moved from `modules/context` to
`services/context` according to design principles. There is no logic
code change on this PR, only move packages.

- Move `code.gitea.io/gitea/modules/context` to
`code.gitea.io/gitea/services/context`
- Move `code.gitea.io/gitea/modules/contexttest` to
`code.gitea.io/gitea/services/contexttest` because of depending on
context
- Move `code.gitea.io/gitea/modules/upload` to
`code.gitea.io/gitea/services/context/upload` because of depending on
context

GustedandEarl Warren c6a53c3172 [SECURITY] Rework long-term authentication
- This is a 'front-port' of the already existing patch on v1.21 and
v1.20, but applied on top of what Gitea has done to rework the LTA
mechanism. Forgejo will stick with the reworked mechanism by the Forgejo
Security team for the time being. The removal of legacy code (AES-GCM) has been
left out.
- The current architecture is inherently insecure, because you can
construct the 'secret' cookie value with values that are available in
the database. Thus provides zero protection when a database is
dumped/leaked.
- This patch implements a new architecture that's inspired from: [Paragonie Initiative](https://paragonie.com/blog/2015/04/secure-authentication-php-with-long-term-persistence#secure-remember-me-cookies).
- Integration testing is added to ensure the new mechanism works.
- Removes a setting, because it's not used anymore.

Fixes #28660
Fixes an admin api bug related to `user.LoginSource`
Fixed `/user/emails` response not identical to GitHub api

This PR unifies the user update methods. The goal is to keep the logic
only at one place (having audit logs in mind). For example, do the
password checks only in one method not everywhere a password is updated.

After that PR is merged, the user creation should be next.

wxiaoguangandGitHub 6913053223 Start using template context function (#26254)
Before:

* `{{.locale.Tr ...}}`
* `{{$.locale.Tr ...}}`
* `{{$.root.locale.Tr ...}}`
* `{{template "sub" .}}`
* `{{template "sub" (dict "locale" $.locale)}}`
* `{{template "sub" (dict "root" $)}}`
* .....

With context function: only need to `{{ctx.Locale.Tr ...}}`

The "ctx" could be considered as a super-global variable for all
templates including sub-templates.


To avoid potential risks (any bug in the template context function
package), this PR only starts using "ctx" in "head.tmpl" and
"footer.tmpl" and it has a "DataRaceCheck". If there is anything wrong,
the code can be fixed or reverted easily.

Bumping `github.com/golang-jwt/jwt` from v4 to v5.

`github.com/golang-jwt/jwt` v5 is bringing some breaking changes:

- standard `Valid()` method on claims is removed. It's replaced by
`ClaimsValidator` interface implementing `Validator()` method instead,
which is called after standard validation. Gitea doesn't seem to be
using this logic.
- `jwt.Token` has a field `Valid`, so it's checked in `ParseToken`
function in `services/auth/source/oauth2/token.go`
