At a glance

CVE-2024-43322 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the Zephyr Project Manager WordPress plugin, affecting versions <= 3.3.100. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 3.3.101; sites on affected versions should update now. Disclosed August 2024, reported by Trương Hữu Phúc (truonghuuphuc).

Vulnerability Overview

The Zephyr Project Manager plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.3.100 via the updateTaskStatus() due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to edit task statuses that do not belong to them.

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 interaction from a victim user.

CWE-639: Authorization Bypass Through User-Controlled Key

Zephyr Project Manager <= 3.3.100 carries this weakness at updateTaskStatus(), and reaching it takes an account at Subscriber level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Zephyr Project Manager the fix is 3.3.101: builds <= 3.3.100 are affected, anything from 3.3.101 onward is not.

Remediation

Update to version 3.3.101, 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: Zephyr Project Manager 3.3.101 closes this, and updating the plugin is the step that ends it.
