CVE-2026-63792 Details
Description
Gitea's collaborative-owner authorization path for reading cross-repository reusable workflows does not exclude fork pull request runs. An approved fork workflow targeting a private repository can read workflow files from another private repository that trusts the base repository's owner through collaborative-owner configuration. The issue exposes private reusable workflow contents at caller-selected Git refs; it does not itself grant write access or code execution in the other repository.
A vulnerability in Gitea's handling of cross-repository reusable workflows allows fork pull requests to access private workflow files from another repository. This issue arises because the authorization check for collaborative ownership does not consider whether the workflow run is from a fork. As a result, an approved fork workflow in a private repository can read workflow files from a different private repository that trusts the base repository's owner through collaborative-owner configuration. The vulnerability exposes private workflow contents at user-selected Git references but does not provide write access or allow code execution in the other repository.
Upgrade to Gitea version 1.27.3, which addresses this vulnerability by enforcing proper trust boundaries for fork pull requests.
