Vulnerability Overview

The Front End PM plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to 11.4.3 (exclusive) via directory listing. This makes it possible for unauthenticated attackers to extract sensitive data including attachments to private messages.

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 Front End PM < 11.4.3 takes a caller who can reach the endpoint. 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 Front End PM the fix is 11.4.3: builds < 11.4.3 are affected, anything from 11.4.3 onward is not.

Remediation

Update to version 11.4.3, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Front End PM 11.4.3 closes this, and updating the plugin is the step that ends it.
