An issue was discovered in xdLocalStorage through 2.0.5.
MEDIUM 6.1EPSS 0.94%
Does this matter?
Lower severity and a low EPSS score (0.94%). Track it; it rarely justifies an emergency change on its own.
Description
An issue was discovered in xdLocalStorage through 2.0.5. The buildMessage() function in xdLocalStorage.js specifies the wildcard (*) as the targetOrigin when calling the postMessage() function on the iframe object. Therefore any domain that is currently loaded within the iframe can receive the messages that the client sends.
