The access map is gated by a `security@: admin.super` guard that is resolved by the field&#8217;s exact path, so a submitted flat dot-notation key such as `access.admin.super` (instead of the nested `access[admin][super]`) matches no blueprint rule, survives BlueprintSchema::filterArray() and flattening, and is written by FlexObject::update() via setNestedProperty(), which splits on `.` and reconstructs the nested value. An authenticated backend operator using the flex accounts backend who holds admin.users but not admin.super can therefore grant admin.super to their own account or to a group they belong to and escalate to full super-admin, gaining control over configuration, plugin and theme installation, the file manager, and all accounts.
