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

Description: An issue was discovered in the receiveMessage() function in xdLocalStorage.js, which does not implement any validation of the origin of web messages. Remote attackers who can entice a user to load a malicious site can exploit this issue to impact the confidentiality and integrity of data in the local storage of the vulnerable site via malicious web messages.

Recommendations: For versions 2.0.5 and earlier, as a temporary workaround, consider disabling the receiveMessage() function until a patch is available. Restrict access to the local storage to minimize the risk of exploitation. Avoid using the vulnerable function to receive messages from untrusted sources until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
