Technical details

The vulnerability is a reflected Cross-Site Scripting (XSS) flaw (CWE-79) in CleverTap Cordova Plugin version 2.6.2 and earlier. The plugin fails to properly validate and sanitize data extracted from deeplinks before using it in JavaScript execution contexts. An attacker can craft a specially formed deeplink that, when opened by a user in an application using the vulnerable plugin, will execute arbitrary JavaScript with the privileges of the application. No authentication is required; the attack requires only that a user click a malicious link. The vulnerability was fixed in version 2.7.0.
