CVE-2023-46647Network attack vector

Editor privilege escalation via bootstrap endpoint requests

Published Dec 21, 2023 · Updated Aug 2, 2024

Improper privilege management in GitHub Enterprise Server allows remote authenticated users with editor access to escalate privileges. The management console permits an editor-role request to its instance-bootstrap endpoint to confer privileges beyond that role. Authorized management-console access with the editor role is required; successful exploitation expands control over the Enterprise Server instance.
