| Affected Software | Affected Version | How to fix |
|---|---|---|
| GitLab | >=13.12<16.2.8 | |
| GitLab | >=16.3.0<16.3.5 | |
| GitLab | =16.4.0 |
Remedy
Upgrade to version 16.2.8, 16.3.5, 16.4.1. If it is not viable to immediately upgrade to a patched version, risk of exploitation can be mitigated by ensuring the [Migrate groups by direct transfer](https://docs.gitlab.com/ee/user/group/import/index.html#migrate-groups-by-direct-transfer-recommended) feature is disabled until GitLab has been upgraded.
