CVE-2023-2589Network attack vector

Public repository cloning bypass via IP restriction check

Published Jun 7, 2023 · Updated Jan 7, 2025

Origin validation error in GitLab EE allows remote attackers to clone public repositories from disallowed IP addresses via Git operations. The group IP-restriction check is bypassed during clone authorization, so requests from blocked addresses are accepted for public projects. The attack requires a public project in a top-level group with IP restrictions; repository contents are disclosed, while write and service-interruption impacts are not indicated.
