At a glance
CVE-2024-32807 is a high-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Brevo for WooCommerce WordPress plugin, affecting versions <= 4.0.17. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Editor level or above. The issue is fixed in version 4.0.18; sites on affected versions should update now. Disclosed April 2024, reported by beluga.
Vulnerability Overview
The Brevo for WooCommerce plugin for WordPress is vulnerable to arbitrary file download and deletion in all versions up to, and including, 4.0.17. This is due to the plugin not properly validating file names in the get_file_contents and delete_attachment functions. This makes it possible for authenticated attackers, with editor-level access and above, to download and delete arbitrary files.
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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Reaching this weakness in Brevo for WooCommerce <= 4.0.17 takes an account at Editor level or above. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.
Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Brevo for WooCommerce the fix is 4.0.18: builds <= 4.0.17 are affected, anything from 4.0.18 onward is not.
Remediation
Update to version 4.0.18, or a newer patched version
How does WordSec protect against this?
An attacker needs Editor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Brevo for WooCommerce 4.0.18 closes this, and updating the plugin is the step that ends it.
