At a glance

CVE-2022-4935 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WCFM Marketplace WordPress plugin, affecting versions <= 3.4.11. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 3.4.12; sites on affected versions should update now. Disclosed April 2023, reported by Chloe Chamberland.

Vulnerability Overview

The WCFM Marketplace plugin for WordPress is vulnerable to unauthorized modification and access of data in versions up to, and including, 3.4.11 due to missing capability checks on various AJAX actions. This makes it possible for authenticated attackers, with minimal permissions such as subscribers, to perform a wide variety of actions such as modifying shipping method details, modifying products, deleting arbitrary posts, and privilege escalation (via the wp_ajax_wcfm_vendor_store_online AJAX action).

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, availability — full site compromise territory.

CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Reaching this weakness in WCFM Marketplace <= 3.4.11 takes a caller who can reach the endpoint. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For WCFM Marketplace the fix is 3.4.12: builds <= 3.4.11 are affected, anything from 3.4.12 onward is not.

Remediation

Update to version 3.4.12, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WCFM Marketplace: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WCFM Marketplace 3.4.12 closes this, and updating the plugin is the step that ends it.
