What the vulnerability does
01Description
The Binary MLM Plan plugin for WordPress is vulnerable to insecure direct object reference in versions up to, and including, 5.0. This is due to the bmp_user_payout_detail_of_current_user() function selecting payout records solely by id without verifying ownership. This makes it possible for authenticated attackers with the bmp_user role (often subscribers) to view other members' payout summaries via direct requests to the /bmp-account-detail/ endpoint with a crafted payout-id parameter granted they can access the shortcode output.
