CVE-2021-22263
A user account with 'external' status which is granted 'Maintainer' role on any project on the GitLab instance where 'project tokens' are allowed may elevate its privilege to 'Internal' and access Internal projects.
Does this matter?
Lower severity and a low EPSS score (1.09%). Track it; it rarely justifies an emergency change on its own.
