At a glance
CVE-2020-36696 is a high-severity Improper Authorization vulnerability in the Product Input Fields for WooCommerce WordPress plugin, affecting versions <= 1.2.6. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 1.2.7; sites on affected versions should update now. Disclosed August 2020, reported by Jerome Bruandet.
Vulnerability Overview
The Product Input Fields for WooCommerce plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the handle_downloads() function in versions up to, and including, 1.2.6. This makes it possible for unauthenticated attackers to download files from the vulnerable service.
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 confidentiality.
CWE-285: Improper Authorization
Product Input Fields for WooCommerce <= 1.2.6 carries this weakness at handle_downloads(), and reaching it takes a caller who can reach the endpoint. 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 Product Input Fields for WooCommerce the fix is 1.2.7: builds <= 1.2.6 are affected, anything from 1.2.7 onward is not.
Remediation
Update to version 1.2.7, 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 Input Fields for WooCommerce 1.2.7 closes this, and updating the plugin is the step that ends it.
