Detailed vulnerability description

The vulnerability allows a remote attacker to redirect victims to arbitrary URL.

The vulnerability exists due to improper sanitization of user-supplied data passed via the "url" HTTP GET parameter to "/wp-content/themes/chrome-extensions/includes/download.php" script. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.

Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.

Example:

http://[host]/wp-content/themes/Divi-child/traitement/billetterie.php?url=https://www.[REDIRECTADDRESS].gov
