CVE-2025-11895
At a glance
CVE-2025-11895 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the Binary MLM Plan WordPress plugin, affecting versions <= 5.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed October 2025, reported by Jonas Benjamin Friedli.
Vulnerability Overview
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.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-639: Authorization Bypass Through User-Controlled Key
Binary MLM Plan <= 5.0 carries this weakness at bmp_user_payout_detail_of_current_user(), and reaching it takes an account at Subscriber level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. No fixed build of this plugin is recorded for Binary MLM Plan yet, so installs running <= 5.0 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
