Gitea versions prior to 1.27.0 contain a vulnerability where a fork pull-request Actions workflow can read a third private repository if that repository trusts the fork's base repository owner as a collaborative owner. This occurs due to a missing permission guard against fork pull-requests in the collaborative-owner branch, resulting in unauthorized read access. The vulnerability leads to a confidentiality breach exposing the full source code of a private repository to an untrusted fork PR author. A patch is available to address this issue.
