A user with read access to a repository could place a commit of their own in it, through a fork pull request or an AGit push, and submit a review naming that commit on a pull request whose head branch is in the same repository. On instances with a runner serving the repository, the attacker\u0027s workflow then ran without approval, received the Actions secrets of the repository and its owner, and got a `GITEA_TOKEN` with write access to the repository. Review-triggered workflows now run on the pull request head."
