CVE-2021-4444 is a high-severity Missing Authorization vulnerability in the Product Filter for WooCommerce by WBW WordPress plugin, affecting versions <= 1.4.9.

Vulnerability Overview

The Product Filter by WooBeWoo plugin for WordPress is vulnerable to authorization bypass in versions up to, and including 1.4.9 due to missing authorization checks on various functions. This makes it possible for unauthenticated attackers to perform unauthorized actions such as creating new filters and injecting malicious javascript into a vulnerable site. This was actively exploited at the time of discovery.

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.

CWE-862: Missing Authorization

Reaching this weakness in Product Filter for WooCommerce by WBW <= 1.4.9 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 Product Filter for WooCommerce by WBW the fix is 1.5.0: builds <= 1.4.9 are affected, anything from 1.5.0 onward is not.

Remediation

Update to version 1.5.0, 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: Product Filter for WooCommerce by WBW 1.5.0 closes this, and updating the plugin is the step that ends it.
