CVE-2020-11611

Name of the Vulnerable Software and Affected Versions xdLocalStorage versions 2.0.5 and earlier

Description An issue was discovered in the buildMessage() function in xdLocalStorage.js, which specifies the wildcard (*) as the targetOrigin when calling the postMessage() function on the iframe object. This allows any domain currently loaded within the iframe to receive the messages that the client sends.

Recommendations For versions 2.0.5 and earlier, consider restricting access to the buildMessage() function in xdLocalStorage.js until a patch is available. As a temporary workaround, avoid using the wildcard (*) as the targetOrigin when calling the postMessage() function on the iframe object to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
