== Security Issue Information ==

 

The 4.5 series update addresses a vulnerability that can permit a malicious user

to decieve a WHMCS installation into crediting a payment that is sent to a

PayPal account other than the account configured within that WHMCS installation.

The 5.x series is unaffected by this vulnerability. It is only possible to

exploit this vulnerability if the paypal module has been activated.

 

The rating for this vulnerability is: important

 

The 4.5 and 5.1 series update addresses a vulnerability that can permit a

malicious user to inject SQL via the Google Checkout module. This only becomes

possible to exploit if the Google Checkout module has been activated within the

WHMCS installation and so non Google Checkout users are not at risk from this.

 

The rating for this vulnerability is: critical
