Upgrading to version 1.1.0-rc1 will fix this issue. Patch name: eccc9d6fbde0c46cdd6e255fd5ce9a30077ba954. You should upgrade the affected component. Affected is a 2013 release where access control was not yet implemented and the endpoint was part of first-run setup). The API key has been admin-gated since 1.2.0 and GET /api/settings is protected by Permissions.SETTINGS_READ plus reauthentication in all current releases.
