At a glance

CVE-2024-11291 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Paid Membership Subscriptions WordPress plugin, affecting versions <= 2.13.4. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.13.5; sites on affected versions should update now. Disclosed December 2024, reported by Francesco Carlucci.

Vulnerability Overview

The Paid Membership Subscriptions – Effortless Memberships, Recurring Payments & Content Restriction plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.13.4 via the WordPress core search feature. This makes it possible for unauthenticated attackers to extract sensitive data from posts that have been restricted to higher-level roles such as logged-in users.

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 privileges on the target site, and no interaction from a victim user.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Paid Membership Subscriptions <= 2.13.4 takes no account at all. 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 Membership Subscriptions the fix is 2.13.5: builds <= 2.13.4 are affected, anything from 2.13.5 onward is not.

Remediation

Update to version 2.13.5, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Paid Membership Subscriptions 2.13.5 closes this, and updating the plugin is the step that ends it.
