Overview
xdlocalstorage is a lightweight js library which implements LocalStorage interface and support cross domain storage by using iframe post message communication.
Affected versions of this package are vulnerable to Exposure of Resource to Wrong Sphere. The postData() function in xdLocalStoragePostMessageApi.js specifies the wildcard (*) as the targetOrigin when calling the postMessage() function on the parent object. Therefore any domain can load the application hosting the "magic iframe" and receive the messages that the "magic iframe" sends.
