In all versions of GitLab CE/EE since version 8.0, an attacker can set the
pipeline schedules to be active in a project export so when an unsuspecting
owner imports that project, pipelines are active by default on that
project. Under specialized conditions, this may lead to information
disclosure if the project is imported from an untrusted source.
