Gitea validated a push mirror's remote address against the `[migrations]` allow and block lists only when the mirror was created. Each synchronization passed the stored address directly to `git push`, so a name that later resolved to a blocked or internal address was still reached. A user with administrator access to a repository, which includes repositories they create themselves, could aim push mirror synchronization at internal Git services and force-push the repository's contents to them.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
