CVE-2020-11610
An issue was discovered in xdLocalStorage through 2.0.5.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.41%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
