At a glance

CVE-2024-9654 is a low-severity Incorrect Authorization vulnerability in the Easy Digital Downloads WordPress plugin, affecting versions 3.1 – 3.3.4. It carries a CVSS score of 3.7 (reachable over the network). Exploitation requires no authentication. The issue is fixed in version 3.3.5; sites on affected versions should update now. Disclosed December 2024, reported by Arkadiusz Hydzik.

Vulnerability Overview

The Easy Digital Downloads plugin for WordPress is vulnerable to Improper Authorization in versions 3.1 through 3.3.4. This is due to a lack of sufficient validation checks within the 'verify_guest_email' function to ensure the requesting user is the intended recipient of the purchase receipt. This makes it possible for unauthenticated attackers to bypass intended security restrictions and view the receipts of other users, which contains a link to download paid content. Successful exploitation requires knowledge of another customers email address as well as the file ID of the content they purchased.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user.

CWE-863: Incorrect Authorization

Easy Digital Downloads 3.1 – 3.3.4 carries this weakness at verify_guest_email, and reaching it takes a caller who can reach the endpoint. Incorrect authorization means a permission check exists but evaluates the wrong thing, so it passes for callers it was meant to stop.

The action runs for users the code intended to exclude, with the same effect as having no check at all. For Easy Digital Downloads the fix is 3.3.5: builds 3.1 – 3.3.4 are affected, anything from 3.3.5 onward is not.

Remediation

Update to version 3.3.5, 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: Easy Digital Downloads 3.3.5 closes this, and updating the plugin is the step that ends it.
