Details

As written in the advisory (Markdown source, shown as plain text).

Mattermost versions 10.5.x <= 10.5.2, 9.11.x <= 9.11.11 fail to check `RestrictSystemAdmin` setting if user doesn't have access to `ExperimentalSettings` which allows a System Manager to access `ExperimentSettings` when `RestrictSystemAdmin` is true via System Console.
