DescriptionA repository created with auto-init accepted pushes before its initialization had finished, and the initial commit was built in a checkout of whatever the repository already contained. A user who is allowed to create repositories could push a crafted tree during that window so that writing the README followed a symbolic link and overwrote a server-side git hook, which runs commands as the Gitea system user. The initial commit is now built in a freshly initialized directory, and a new repository only becomes ready, and accepts pushes, once its initialization is complete.
