What is CVE-2026-70400?
CVE-2026-70400 is a medium-severity missing authorization vulnerability in Gitea, published on 14 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
