GitLab has remediated an issue in GitLab EE affecting all versions from 18.8 before 18.10.7, 18.11 before 18.11.4, and 19.0 before 19.0.1 that, under certain conditions, could have allowed an authenticated user to cause specific Duo AI workflows to run under another user's identity due to improper user identity resolution when triggering Duo AI workflow runners.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 9b94eb13-6159-11f1-be36-2cf05da270f3 advisory.
