High (8.8) in cross domain local storage project cross domain local storage. EPSS 1.4% chance of exploitation in the next 30 days.
An issue was discovered in xdLocalStorage through 2.0.5. 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 "magical iframe" and receive the messages that the "magical iframe" sends.
