## 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>
