Composer fails with permissions

[evs-xsarus]

Expected Behavior

Composer install should run without issues.

Current Behavior

Composer fails with permission errors:

$ cd magento/
$ composer config gitlab-token.git.xsarus.net gitlab-ci-token "${CI_JOB_TOKEN}"
The repository at "/builds/shm/webshop-magento/magento" does not have the correct ownership and git refuses to use it:
fatal: detected dubious ownership in repository at '/builds/shm/webshop-magento'

In Filesystem.php line 913:
                                                                               
  file_put_contents(/builds/shm/webshop-magento/magento/vendor/composer/installed.php): Failed to open stream: Permission denied
