GMS-2020-309: Cross-Site Scripting in jquery-mobile
(updated )
All version of jquery-mobile are vulnerable to Cross-Site Scripting. The package checks for content in location.hash and if a URL is found it does an XmlHttpRequest (XHR) to the URL and renders the response with innerHTML. It fails to validate the Content-Type of the response, allowing attackers to include malicious payloads as part of query parameters that are reflected back to the user. A response such as {"q":"<iframe/src='javascript:alert(1)'></iframe>","results":[]} would be parsed as HTML and the JavaScript payload executed. No fix is currently available. Consider using an alternative package until a fix is made available.
