Advisory

Source description from Wordfence Intelligence, credited to Francesco Carlucci.

The EAN for WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.9.2 via the the 'alg_wc_ean_product_meta' shortcode due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to expose potentially sensitive post metadata.
