CVE-2026-103367: File Inclusion (CVSS 8.1)

Description

The ShopMagic – email automation for WordPress plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.9.0 via the 'billing_address.first_name' parameter parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included. Exploitation requires a published recipe that processes the {{ customer.first_name }} placeholder — the plugin's built-in "New Order email with social media profile links" recipe satisfies this requirement out of the box, making the default configuration exploitable with no account, cookie, or nonce by simply submitting a guest checkout with the payload as the billing first name.
