GitHub Security was notified about an issue where users still had access to organizations after being removed. Our Security team investigated potential instances and determined there were occasional instances where users’ permissions were not fully removed when teams were deleted or they were part of a team when they were removed from the organization. While we investigated the root causes, which stemmed from background job and permissions issues, a manual fix has been implemented since October 20, 2022. We have addressed the underlying issues and the need for the previously implemented manual fix. We have also cleaned up any users that were not removed when they should have been. There is no further action that is required by any organization.
