This PR is part of a series (#11311). If the user authenticating to an API call is a Forgejo site administrator, or a Forgejo repo administrator, a wide variety of permission and ownership checks in the API are either bypassed, or are bypassable. If a user has created an access token with restricted resources, I understand the intent of the user is to create a token which has a layer of risk reduction in the event that the token is lost/leaked to an attacker. For this reason, it makes sense to me that restricted scope access tokens shouldn't inherit the owner's administrator access. My intent is that repo-specific access tokens [will only be able to access specific authorization scopes](https://codeberg.org/forgejo/design/issues/50#issuecomment-11093951), probably: `repository:read`, `repository:write`, `issue:read`, `issue:write`, (`organization:read` / `user:read` maybe). This means that *most* admin access is not intended to be affected by this because repo-specific access tokens won't have, for example, `admin:write` scope. However, administrative access still grants elevated permissions in some areas that are relevant to these scopes, and need to be restricted: - The `?sudo=otheruser` query parameter allows site administrators to impersonate other users in the API. - Repository management rules are different for a site administrator, allowing them to create repos for another user, create repos in another organization, migrate a repository to an arbitrary owner, and transfer a repository to a prviate organization. - Administrators have access to extra data through some APIs which would be in scope: the detailed configuration of branch protection rules, the some details of repository deploy keys (which repo, and which scope -- seems odd), (user:read -- user SSH keys, activity feeds of private users, user profiles of private users, user webhook configurations). - Pull request reviews have additional perms for repo administrators, including the ability to dismiss PR reviews, delete PR reviews, and view draft PR reviews. - Repo admins and site admins can comment on locked issues, and related to comments can edit or delete other user's comments and attachments. - Repo admins can manage and view logged time on behalf of other users. A handful of these permissions may make sense for repo-specific access tokens, but most of them clearly exceed the risk that would be expected from creating a limited scope access token. I'd generally prefer to take a restrictive approach, and we can relax it if real-world use-cases come in -- users will have a workaround of creating an access token without repo-specific restrictions if they are blocked from needed access. **Breaking:** The administration restrictions introduced in this PR affect both repo-specific access tokens, and existing public-only access tokens. ## Checklist The [contributor guide](https://forgejo.org/docs/next/contributor/) contains information that will be helpful to first time contributors. There also are a few [conditions for merging Pull Requests in Forgejo repositories](https://codeberg.org/forgejo/governance/src/branch/main/PullRequestsAgreement.md). You are also welcome to join the [Forgejo development chatroom](https://matrix.to/#/#forgejo-development:matrix.org). ### Tests for Go changes (can be removed for JavaScript changes) - I added test coverage for Go changes... - [x] in their respective `*_test.go` for unit tests. - [x] in the `tests/integration` directory if it involves interactions with a live Forgejo server. - I ran... - [x] `make pr-go` before pushing ### Documentation - [ ] I created a pull request [to the documentation](https://codeberg.org/forgejo/docs) to explain to Forgejo users how to use this change. - [x] I did not document these changes and I do not expect someone else to do it. ### Release notes - [x] This change will be noticed by a Forgejo user or admin (feature, bug fix, performance, etc.). I suggest to include a release note for this change. - Although repo-specific access tokens are not yet exposed to end users, the breaking changes to public-only tokens will be visible to users and require release notes. - [ ] This change is not visible to a Forgejo user or admin (refactor, dependency upgrade, etc.). I think there is no need to add a release note for this change.
