At a glance

CVE-2025-11271 is a medium-severity Reliance on Untrusted Inputs in a Security Decision vulnerability in the Easy Digital Downloads WordPress plugin, affecting versions <= 3.5.2. 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 3.5.3; sites on affected versions should update now. Disclosed November 2025, reported by Jay.

Vulnerability Overview

The Easy Digital Downloads plugin for WordPress is vulnerable to Order Manipulation in all versions up to, and including, 3.5.2 due to an order verification bypass. The verification is unconditionally skipped when the POST body includes verification_override=1. Because this value is attacker-supplied, an unauthenticated actor can submit a forged IPN and have it treated as verified, even on production sites and with verification otherwise enabled. A valid PayPal transaction id is needed, restricting order manipulation to orders placed by the attacker. This, in turn, requires them to have a customer account.

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-807: Reliance on Untrusted Inputs in a Security Decision

The product uses a protection mechanism that relies on the existence or values of an input, but the input can be modified by an untrusted actor in a way that bypasses the protection mechanism.

Remediation

Update to version 3.5.3, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Easy Digital Downloads 3.5.3 closes this, and updating the plugin is the step that ends it.
