CVE-2026-63792Network attack vectorHinoki check available

Workflow disclosure via unchecked fork-run owner trust

Published Oct 14, 2026 · Updated Oct 14, 2026

Authorization bypass in Gitea Actions 1.27.2 and earlier allows remote authenticated users to read private workflows via fork runs. CanReadWorkflowCrossRepo grants collaborative-owner access without excluding fork pull request runs, exposing reusable workflow files at caller-selected Git refs. The run must target a private repository, receive approval, and access another private repository that trusts the base repository's owner; disclosure is confined to configured workflow directories and grants no write access or code execution.
