In April 2021, GitLab disclosed CVE-2021-22205 detailing a trivial Remote Code Execution vulnerability. “Trivial” meaning that it is both (1) easy to execute and (2) can be done by unauthenticated users. On November 1st, this vulnerability was found being actively exploited in the wild, including DigitalOcean customers. We strongly encourage you to:
