* Add ability to set multiple redirect URIs in OAuth application UI (#25072)Denys Konovalov2023-06-051-8/+0
| | | | | | | | | | | | | | | | | | | | OAuth applications can already have multiple redirect URIs if created/edited over API. This change allows for setting multiple redirect URIs through the UI as a comma-separated list (e. g. `https://example.org/redirect,https://redirect.example.org`) <details> <summary>Screenshots</summary> ![Bildschirmfoto vom 2023-06-04 17-14-40](https://github.com/go-gitea/gitea/assets/47871822/2206dc32-e7e4-4953-9ecb-e098890b3f54) ![Bildschirmfoto vom 2023-06-04 17-14-50](https://github.com/go-gitea/gitea/assets/47871822/cd97c73c-9310-44ee-a83a-b927a1ef94da) </details> Closes #25068
* Redesign Scoped Access Tokens (#24767)Jack Hay2023-06-043-187/+276
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## Changes - Adds the following high level access scopes, each with `read` and `write` levels: - `activitypub` - `admin` (hidden if user is not a site admin) - `misc` - `notification` - `organization` - `package` - `issue` - `repository` - `user` - Adds new middleware function `tokenRequiresScopes()` in addition to `reqToken()` - `tokenRequiresScopes()` is used for each high-level api section - _if_ a scoped token is present, checks that the required scope is included based on the section and HTTP method - `reqToken()` is used for individual routes - checks that required authentication is present (but does not check scope levels as this will already have been handled by `tokenRequiresScopes()` - Adds migration to convert old scoped access tokens to the new set of scopes - Updates the user interface for scope selection ### User interface example <img width="903" alt="Screen Shot 2023-05-31 at 1 56 55 PM" src="https://github.com/go-gitea/gitea/assets/23248839/654766ec-2143-4f59-9037-3b51600e32f3"> <img width="917" alt="Screen Shot 2023-05-31 at 1 56 43 PM" src="https://github.com/go-gitea/gitea/assets/23248839/1ad64081-012c-4a73-b393-66b30352654c"> ## tokenRequiresScopes Design Decision - `tokenRequiresScopes()` was added to more reliably cover api routes. For an incoming request, this function uses the given scope category (say `AccessTokenScopeCategoryOrganization`) and the HTTP method (say `DELETE`) and verifies that any scoped tokens in use include `delete:organization`. - `reqToken()` is used to enforce auth for individual routes that require it. If a scoped token is not present for a request, `tokenRequiresScopes()` will not return an error ## TODO - [x] Alphabetize scope categories - [x] Change 'public repos only' to a radio button (private vs public). Also expand this to organizations - [X] Disable token creation if no scopes selected. Alternatively, show warning - [x] `reqToken()` is missing from many `POST/DELETE` routes in the api. `tokenRequiresScopes()` only checks that a given token has the correct scope, `reqToken()` must be used to check that a token (or some other auth) is present. - _This should be addressed in this PR_ - [x] The migration should be reviewed very carefully in order to minimize access changes to existing user tokens. - _This should be addressed in this PR_ - [x] Link to api to swagger documentation, clarify what read/write/delete levels correspond to - [x] Review cases where more than one scope is needed as this directly deviates from the api definition. - _This should be addressed in this PR_ - For example: ```go m.Group("/users/{username}/orgs", func() { m.Get("", reqToken(), org.ListUserOrgs) m.Get("/{org}/permissions", reqToken(), org.GetUserOrgsPermissions) }, tokenRequiresScopes(auth_model.AccessTokenScopeCategoryUser, auth_model.AccessTokenScopeCategoryOrganization), context_service.UserAssignmentAPI()) ``` ## Future improvements - [ ] Add required scopes to swagger documentation - [ ] Redesign `reqToken()` to be opt-out rather than opt-in - [ ] Subdivide scopes like `repository` - [ ] Once a token is created, if it has no scopes, we should display text instead of an empty bullet point - [ ] If the 'public repos only' option is selected, should read categories be selected by default Closes #24501 Closes #24799 Co-authored-by: Jonathan Tran <jon@allspice.io> Co-authored-by: Kyle D <kdumontnu@gmail.com> Co-authored-by: silverwind <me@silverwind.io>

* Support scoped access tokens (#20908)Chongyi Zheng2023-01-173-0/+336
| | | | | | | | | | | | | | | | | | | | | | | | | | | This PR adds the support for scopes of access tokens, mimicking the design of GitHub OAuth scopes. The changes of the core logic are in `models/auth` that `AccessToken` struct will have a `Scope` field. The normalized (no duplication of scope), comma-separated scope string will be stored in `access_token` table in the database. In `services/auth`, the scope will be stored in context, which will be used by `reqToken` middleware in API calls. Only OAuth2 tokens will have granular token scopes, while others like BasicAuth will default to scope `all`. A large amount of work happens in `routers/api/v1/api.go` and the corresponding `tests/integration` tests, that is adding necessary scopes to each of the API calls as they fit. - [x] Add `Scope` field to `AccessToken` - [x] Add access control to all API endpoints - [x] Update frontend & backend for when creating tokens - [x] Add a database migration for `scope` column (enable 'all' access to past tokens) I'm aiming to complete it before Gitea 1.19 release.

* Improve utils of slices (#22379)Jason Song2023-01-111-2/+2
| | | | | | | | | | | | | | | | | | | - Move the file `compare.go` and `slice.go` to `slice.go`. - Fix `ExistsInSlice`, it's buggy - It uses `sort.Search`, so it assumes that the input slice is sorted. - It passes `func(i int) bool { return slice[i] == target })` to `sort.Search`, that's incorrect, check the doc of `sort.Search`. - Conbine `IsInt64InSlice(int64, []int64)` and `ExistsInSlice(string, []string)` to `SliceContains[T]([]T, T)`. - Conbine `IsSliceInt64Eq([]int64, []int64)` and `IsEqualSlice([]string, []string)` to `SliceSortedEqual[T]([]T, T)`. - Add `SliceEqual[T]([]T, T)` as a distinction from `SliceSortedEqual[T]([]T, T)`. - Redesign `RemoveIDFromList([]int64, int64) ([]int64, bool)` to `SliceRemoveAll[T]([]T, T) []T`. - Add `SliceContainsFunc[T]([]T, func(T) bool)` and `SliceRemoveAllFunc[T]([]T, func(T) bool)` for general use. - Add comments to explain why not `golang.org/x/exp/slices`. - Add unit tests.

* Replace fmt.Sprintf with hex.EncodeToString (#21960)Jason Song2022-11-281-1/+2
| | | | | | | | | | | | | | | | | | | | | `hex.EncodeToString` has better performance than `fmt.Sprintf("%x", []byte)`, we should use it as much as possible. I'm not an extreme fan of performance, so I think there are some exceptions: - `fmt.Sprintf("%x", func(...)[N]byte())` - We can't slice the function return value directly, and it's not worth adding lines. ```diff func A()[20]byte { ... } - a := fmt.Sprintf("%x", A()) - a := hex.EncodeToString(A()[:]) // invalid + tmp := A() + a := hex.EncodeToString(tmp[:]) ``` - `fmt.Sprintf("%X", []byte)` - `strings.ToUpper(hex.EncodeToString(bytes))` has even worse performance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OAuth spec [defines two types of client](https://datatracker.ietf.org/doc/html/rfc6749#section-2.1), confidential and public. Previously Gitea assumed all clients to be confidential. > OAuth defines two client types, based on their ability to authenticate securely with the authorization server (i.e., ability to > maintain the confidentiality of their client credentials): > > confidential > Clients capable of maintaining the confidentiality of their credentials (e.g., client implemented on a secure server with > restricted access to the client credentials), or capable of secure client authentication using other means. > > **public > Clients incapable of maintaining the confidentiality of their credentials (e.g., clients executing on the device used by the resource owner, such as an installed native application or a web browser-based application), and incapable of secure client authentication via any other means.** > > The client type designation is based on the authorization server's definition of secure authentication and its acceptable exposure levels of client credentials. The authorization server SHOULD NOT make assumptions about the client type. https://datatracker.ietf.org/doc/html/rfc8252#section-8.4 > Authorization servers MUST record the client type in the client registration details in order to identify and process requests accordingly.

* Make every not exist error unwrappable to a fs.ErrNotExist (#20891)zeripath2022-10-185-1/+41
| | | | | | | | | | | | | | | | | | | | A lot of our code is repeatedly testing if individual errors are specific types of Not Exist errors. This is repetitative and unnecesary. `Unwrap() error` provides a common way of labelling an error as a NotExist error and we can/should use this. This PR has chosen to use the common `io/fs` errors e.g. `fs.ErrNotExist` for our errors. This is in some ways not completely correct as these are not filesystem errors but it seems like a reasonable thing to do and would allow us to simplify a lot of our code to `errors.Is(err, fs.ErrNotExist)` instead of `package.IsErr...NotExist(err)` I am open to suggestions to use a different base error - perhaps `models/db.ErrNotExist` if that would be felt to be better.

| | | | | | | | | | | | | WebAuthn have updated their specification to set the maximum size of the CredentialID to 1023 bytes. This is somewhat larger than our current size and therefore we need to migrate.
