Auth bypass in Warpgate Project

CVE-2023-37268

Any user account which does not have a second factor enabled could be compromised. This issue has been addressed in commit `8173f6512a` and in releases starting with version 0.7.3. Users are advised to upgrade. Users unable to upgrade should require their users to use a second factor in authentication.
