Gitea's pull request review notifier does not attach the pull request to the Actions notification, so the fork workflow approval gate does not recognize the run as originating from a fork. Review comment and review approval or rejection events can consequently load workflow code from the fork head and run it on the base repository's runners without the required maintainer approval. This allows execution of fork-controlled workflow code across the intended approval boundary.
