At a glance
CVE-2026-2421 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the ilGhera Carta Docente for WooCommerce WordPress plugin, affecting versions <= 1.5.0. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 1.5.1; sites on affected versions should update now. Disclosed March 2026, reported by Legion Hunter.
Vulnerability Overview
The ilGhera Carta Docente for WooCommerce plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.5.0 via the 'cert' parameter of the 'wccd-delete-certificate' AJAX action. This is due to insufficient file path validation before performing a file deletion. This makes it possible for authenticated attackers, with Administrator-level access and above, to delete arbitrary files on the server, such as wp-config.php, which can make site takeover and remote code execution possible.
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 integrity, availability.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
ilGhera Carta Docente for WooCommerce <= 1.5.0 carries this weakness at cert, and reaching it takes an account at Administrator 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 ilGhera Carta Docente for WooCommerce the fix is 1.5.1: builds <= 1.5.0 are affected, anything from 1.5.1 onward is not.
Remediation
Update to version 1.5.1, or a newer patched version
How does WordSec protect against this?
An attacker needs Administrator 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: ilGhera Carta Docente for WooCommerce 1.5.1 closes this, and updating the plugin is the step that ends it.
