Description

Using the Gitea API it is currrently possible with the new commit status endpoint to add a commit status to a repository, even if you don't have write access to that repository. This function does not check, if the user has access to the repository.

Gitea Version

from 1.16.8 to 1.18.0+dev-90-gc8e0fd0bc

Can you reproduce the bug on the Gitea demo site?

Yes

    Ensure that drone tags 1.16.x and 1.16 on push to v1.16.x tag (go-gitea#20304)

    We need pushes to v1.16.9 to create tags to 1.16.9 and 1.16 but not 1 or latest.

    We have previously adjusted the manifest to remove the latest tag, and have removed
    auto_tags so that 1 does not get tagged but in doing so we also stopped 1.16 being
    tagged. So here we just state the that we tag x.yy in addition to x.yyz*.
