CVE-2026-70400— Gitea private migration creation with public-only tokens

Quick assessment

Affected
Gitea Gitea
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Gitea 的仓库迁移 API 在接受仅具备公开访问权限的令牌时，若请求指定创建私有仓库，则允许通过验证。一个仅被授权操作公开资源的委派令牌，可以在授权用户或该用户拥有相应权限的组织下，创建私有仓库及迁移任务。而普通的私有仓库创建路由会拒绝使用此类令牌，但迁移路径却缺少这一限制。

Vulnerability Title
Gitea private migration creation with public-only tokens
Source: CVE Program / CVE List V5
Vulnerability Description
Gitea's repository migration API accepts a public-only token when the request specifies creation of a private repository. A delegated token intended to operate only on public resources can create a private repository and migration task under the authorizing account or an organization where that user has the necessary permissions. The ordinary private repository-creation route rejects the same token, but the migration path omits that restriction.
