$wps_limit_login_white_list_ips = $this->get_option( 'wps_qlimit_login_whitelist' );

$wps_limit_login_white_list_ips = ( is_array( $wps_limit_login_white_list_ips ) && ! empty( $wps_limit_login_white_list_ips ) ) ? implode( "\n", $wps_limit_login_white_list_ips ) : '';

4) Cross-site request forgery (CVE-ID: N/A)

The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin in the "/classes/plugin.php" file . A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.
