Vulnerability Overview

The Paid Memberships Pro – Content Restriction, User Registration, & Paid Subscriptions plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.12.8. This makes it possible for authenticated attackers, with contributor-level access and above, to extract user meta data utilizing the pmpro_member shortcode.

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-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Paid Memberships Pro <= 2.12.8 takes an account at Contributor level or above. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Paid Memberships Pro the fix is 2.12.9: builds <= 2.12.8 are affected, anything from 2.12.9 onward is not.

Remediation

Update to version 2.12.9, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Paid Memberships Pro 2.12.9 closes this, and updating the plugin is the step that ends it.
