Gitea: Token public-only scope bypassed on Limited-visibility owners (Repository + Package categories) — residual after CVE-2026-25714 / PR #37118
## Summary After [PR #37118](https://github.com/go-gitea/gitea/pull/37118) / **CVE-2026-25714** (`fix: Unify public-only token filtering in API queries and repo access checks`, merged 2026-05-18, backport `#37773` to 1.26.2 — the May 2026 unification pass for public-only token filtering, reporter Medoedus per the 1.26.2 release notes), the `public-only` PAT scope is still bypassable on **Repository** and **Package** scope categories when the owner's `Visibility = Limited` (instance-internal). The sibling `Org` / `User` / `ActivityPub` cases in the same `checkTokenPublicOnly` switch correctly reject Limited owners via `!Visibility.IsPublic()`. The Repository / Package cases use `repo.IsPrivate` or `Owner.Visibility.IsPrivate()`, both of which return `false` for `VisibleTypeLimited` — so a `public-only` PAT strictly exceeds anonymous reach on a Limited owner. Tested on `gitea/gitea:1.26.2`. The decisive marker is that PR #37118's unification IS applied in the version under test (User-category PROBE returns `403 "token scope is limited to public users"`). Despite that, the Repository-category PROBE on the same Limited owner with the same PAT returns `200` and serves content. ## Affected entry points (4 spots) | File:Line | Function | Affected surface | |---|---|---| | `routers/api/v1/api.go:292` | `checkTokenPublicOnly` Package case | API v1 packages | | `routers/api/packages/api.go:76` | `reqPackageAccess` middleware | All 24 native package registries (`/api/packages//...`) | |
