CVE-2026-63792 is an authorization flaw in Gitea's CanReadWorkflowCrossRepo access-control function. The collaborative-owner authorization path permits cross-repository reads of reusable workflow files without determining whether the Actions run originated from a fork pull request. Consequently, an approved fork pull-request workflow run against one private repository can retrieve reusable workflow contents from another private repository that trusts the first repository's owner as a collaborative owner. The requested Git reference is attacker-controlled, although reads remain limited to configured workflow directories.

A Gitea security vulnerability addressed by the available package update; no individual flaw details are supplied.
An insufficient-authorization flaw in Gitea's CanReadWorkflowCrossRepo logic that permits an approved fork pull-request workflow run to read private reusable workflow files from a cross-repository collaborative owner relationship. The issue provides read-only disclosure of workflow contents and does not grant write access or code execution.
