At a glance

CVE-2026-16777 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Store Exporter WordPress plugin, affecting versions <= 2.8.0. It carries a CVSS score of 4.9 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Shop Manager level or above. The issue is fixed in version 2.8.1; sites on affected versions should update now. Disclosed September 2026, reported by Wordfence PRISM.

Vulnerability Overview

The Store Exporter – Export WooCommerce Products, Orders, Subscriptions, Customers plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.8.0 via the 'filename' parameter parameter. This makes it possible for authenticated attackers, with shop manager-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.

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.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Store Exporter <= 2.8.0 carries this weakness at filename, and reaching it takes an account at Shop Manager 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 Store Exporter the fix is 2.8.1: builds <= 2.8.0 are affected, anything from 2.8.1 onward is not.

Remediation

Update to version 2.8.1, or a newer patched version

How does WordSec protect against this?

An attacker needs Shop Manager 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: Store Exporter 2.8.1 closes this, and updating the plugin is the step that ends it.
