fix(migrations): prevent path traversal in repository restore (#38215)
## Problem

The repository restorer (`services/migrations/restore.go`) builds
`file://` URLs for release attachments and PR patches by joining
user-supplied paths from `release.yml` and `pull_request.yml` onto the
dump directory:

```go
*asset.DownloadURL = "file://" + filepath.Join(r.baseDir, *asset.DownloadURL)
pr.PatchURL        = "file://" + filepath.Join(r.baseDir, pr.PatchURL)
```

`filepath.Join` cleans the path, so a crafted relative value such as
`../../../../etc/passwd` resolves to an absolute path **outside** the
dump directory. `uri.Open` then reads it via `os.Open` and stores the
content as a release attachment, which is retrievable through the API —
an arbitrary file read (Local File Inclusion) from a dump archive
supplied to `restore-repo`.

## Fix

Add a `localFileURL` helper that resolves the relative path against
`baseDir` and rejects anything that escapes it. Malicious entries are
skipped with a warning so a legitimate restore still completes; in-dump
files keep working unchanged.

Gitea

繁體中文 | 简体中文

Purpose

The goal of Gitea is to make the easiest, fastest, and most painless way of setting up a self-hosted all-in-one software development service, including Git hosting, code management, code review, issue tracking, project kanban, wiki, team collaboration, package registry and CI/CD which can reuse GitHub Actions.

As Gitea is written in Go, it works across all the platforms and architectures that are supported by Go, including Linux, macOS, FreeBSD/OpenBSD and Windows on x86, amd64, ARM, RISC-V 64 and PowerPC architectures.

For online demonstrations, you can visit demo.gitea.com.

For accessing free Gitea service (with a limited number of repositories), you can visit gitea.com.

To quickly deploy your own dedicated Gitea instance on Gitea Cloud, you can start a free trial at cloud.gitea.com, or use container (docker/podman/etc) to deploy on your own server with the official image.

Documentation

You can find comprehensive documentation on our official documentation website.

It includes installation, administration, usage, development, contributing guides, and more to help you get started and explore all features effectively.

If you have any suggestions or would like to contribute to it, you can visit the documentation repository

Building

See docs/build-setup.md for prerequisites and docs/development.md for setting up a local development environment, linting, and testing.

If you'd like to build from source or make a distribution package, see docs/build-source.md for more information.

After building, you can run ./gitea web to start the server, or ./gitea help to see all available commands.

Contributing

Expected workflow is: Fork -> Patch -> Push -> Pull Request

Note

  1. YOU MUST READ THE CONTRIBUTORS GUIDE BEFORE STARTING TO WORK ON A PULL REQUEST.
  2. New to the codebase? The development guide walks through setting up a local environment and building from source.
  3. If you have found a vulnerability in the project, please write privately to security@gitea.io. Thanks!

Translating

Crowdin

Translations are done through Crowdin. If you want to translate to a new language, ask one of the managers in the Crowdin project to add a new language there.

You can also just create an issue for adding a language or ask on Discord on the #translation channel. If you need context or find some translation issues, you can leave a comment on the string or ask on Discord. For general translation questions there is a section in the docs. Currently a bit empty, but we hope to fill it as questions pop up.

Get more information from documentation.

Official and Third-Party Projects

We provide an official go-sdk, a CLI tool called tea and an action runner for Gitea Action.

We maintain a list of Gitea-related projects at gitea/awesome-gitea, where you can discover more third-party projects, including SDKs, plugins, themes, and more.

Communication

If you have questions that are not covered by the documentation, you can get in contact with us on our Discord server or create a post in the discourse forum.
