Exploited in the last 30 days

Plane is an open-source project management tool. Prior to 1.4.0, WorkspaceOwnerPermission does not require is_active=True when checking whether a user is a workspace owner. A deactivated user can therefore remain authorized as the workspace owner and retain owner-level access. This issue is fixed in 1.4.0.
