Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Gitea versions before 1.27.0 (packages code.gitea.io/gitea and gitea.dev) have a server-side request forgery flaw in migration asset downloads and some OAuth paths, which use plain HTTP requests that skip the project's internal-address protection and also accept file:// URLs. An attacker who can start a migration (admin or organization owner rights) or who controls an admin-configured custom OAuth2 source could read local files and reach internal or cloud metadata services. Upgrade to Gitea 1.27.0 or later.
