Summary

CleverTap Cordova Plugin version 2.6.2 allows a remote attacker to execute JavaScript code in any application that is opened via a specially constructed deeplink by an attacker.

This is possible because the plugin does not correctly validate the data coming from the deeplinks before using them.
