At a glance

This record tracks a critical-severity Missing Authorization vulnerability in the Atarim WordPress plugin, affecting versions < 3.9.2. It carries a CVSS score of 9.1 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.9.2; sites on affected versions should update now. Disclosed July 2023.

Vulnerability Overview

The Atarim - Client Interface plugin for WordPress is vulnerable to unauthorized use of functionality due to a missing capability check on the avc_send_invitations and avc_delete_invitations functions in versions up to, and including, 3.9.1. This makes it possible for unauthenticated attackers to delete arbitrary accounts (and the content they created) on the site. The creation of accounts is also possible although new accounts are limited to the default role or subscriber, whichever is higher.

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 integrity, availability.

CWE-862: Missing Authorization

Reaching this weakness in Atarim < 3.9.2 takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Atarim the fix is 3.9.2: builds < 3.9.2 are affected, anything from 3.9.2 onward is not.

Remediation

Update to version 3.9.2, 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: Atarim 3.9.2 closes this, and updating the plugin is the step that ends it.
