Missing permission check on fork relation creation in GitLab CE/EE 11.3 and later through 13.0.1 allows guest users to create a fork relation on restricted public projects via API

An information disclosure vulnerability in GitLab CE/EE versions 12.0 to 14.3.6, 14.4 to 14.4.4, and 14.5 to 14.5.2 allowed non-project members to see the default branch name for projects that restrict access to the repository to project members

In all versions of GitLab EE since version 8.13, an endpoint discloses names of private groups that have access to a project to low privileged users that are part of that project.

In all versions of GitLab EE since version 14.1, due to an insecure direct object reference vulnerability, an endpoint may reveal the protected branch name to a malicious user who makes a crafted API call with the ID of the protected branch.

In all versions of GitLab CE/EE since version 12.0, a lower privileged user can import users from projects that they don't have a maintainer role on and disclose email addresses of those users.

In all versions of GitLab CE/EE since version 13.6, it is possible to see pending invitations of any public group or public project by visiting an API endpoint.

Improper authorization in GitLab CE/EE affecting all versions since 13.0 allows guests in private projects to view CI/CD analytics

Improper validation of invited users' email address in GitLab EE affecting all versions since 12.2 allowed projects to add members with email address domain that should be blocked by group settings

An issue has been discovered in GitLab affecting all versions starting from 13.4. Improper access control allows unauthorized users to access details on analytic pages.
