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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":220336,"id":"CVE-2026-63792","ts":1791996228167,"field":"cvss","old":null,"new":"5.3"},{"seq":220335,"id":"CVE-2026-63792","ts":1791996228167,"field":"severity","old":"none","new":"medium"}]}
