What fixes it

No source in this snapshot names a fixed version. The vendor advisories under References are the place to check.

Description

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.
