At a glance

CVE-2023-30869 is a critical-severity Unverified Password Change vulnerability in the Easy Digital Downloads WordPress plugin, affecting versions 3.1 – < 3.1.1.4.2. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.1.1.4.2; sites on affected versions should update now. Disclosed May 2023, reported by Nguyen Anh Tien.

Vulnerability Overview

The Easy Digital Downloads plugin for WordPress is vulnerable to Unauthenticated Arbitrary Password Resets to Privilege Escalation in versions 3.1 to 3.1.1.4.1. This is due to a lack of validation of a password reset key in the edd_validate_password_reset function. This makes it possible for unauthenticated attackers to reset the password of any user on a vulnerable site, including an administrator, if they have the email or username of the targeted 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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-620: Unverified Password Change

Reaching this weakness in Easy Digital Downloads 3.1 – < 3.1.1.4.2 takes no account at all. Unverified password change means the password-update path does not require proof that the requester is the account owner.

An attacker who can reach the endpoint takes over the account outright, and the legitimate owner is locked out of it. For Easy Digital Downloads the fix is 3.1.1.4.2: builds 3.1 – < 3.1.1.4.2 are affected, anything from 3.1.1.4.2 onward is not.

Remediation

Update to version 3.1.1.4.2, 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: Easy Digital Downloads 3.1.1.4.2 closes this, and updating the plugin is the step that ends it.
