At a glance

CVE-2024-7624 is a high-severity Improper Authorization vulnerability in the Zephyr Project Manager WordPress plugin, affecting versions <= 3.3.101. It carries a CVSS score of 8.1 (reachable over the network; low attack complexity; high confidentiality, integrity impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 3.3.102; sites on affected versions should update now. Disclosed August 2024, reported by wesley (wcraft).

Vulnerability Overview

The Zephyr Project Manager plugin for WordPress is vulnerable to limited privilege escalation in all versions up to, and including, 3.3.101. This is due to the plugin not properly checking a users capabilities before allowing them to enable access to the plugin's settings through the update_user_access() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to grant themselves full access to the plugin's settings.

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. A successful exploit has high impact on confidentiality, integrity.

CWE-285: Improper Authorization

Zephyr Project Manager <= 3.3.101 carries this weakness at update_user_access(), and reaching it takes an account at Subscriber level or above. Improper authorization means a permission check exists but does not cover the case being exercised, so a caller who is allowed to do one thing is allowed to do a neighbouring thing as well.

A lower-privileged account performs an action reserved for a higher one, which on a multi-author or membership site means an ordinary user reaching administrative behaviour. For Zephyr Project Manager the fix is 3.3.102: builds <= 3.3.101 are affected, anything from 3.3.102 onward is not.

Remediation

Update to version 3.3.102, 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 3.3.102 closes this, and updating the plugin is the step that ends it.
