Exploited in the wild: not listed in CISA KEV
EPSS: 0.4% probability of exploitation in the next 30 days

Weakness: CWE-863

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.
