Vulnerability Overview
The Paid Memberships Pro - Member Directory Add On plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to 1.2.6 (exclusive) through the 'pmpro_member_directory' shortcode. This makes it possible for authenticated attackers, with contributor-level access and above, to extract sensitive user meta data, including password hashes.
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
Paid Memberships Pro - Member Directory Add On < 1.2.6 carries this weakness at pmpro_member_directory, and reaching it takes an account at Contributor 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. For Paid Memberships Pro - Member Directory Add On the fix is 1.2.6: builds < 1.2.6 are affected, anything from 1.2.6 onward is not.
Remediation
Update to version 1.2.6, or a newer patched version
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. None of that substitutes for the fix: Paid Memberships Pro - Member Directory Add On 1.2.6 closes this, and updating the plugin is the step that ends it.
