## What is CVE-2026-2421?

CVE-2026-2421 is a medium-severity path traversal vulnerability in ghera74 ilGhera Carta Docente for WooCommerce, published on 20 Mar 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

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.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)
