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.

Detection & mitigation playbook

Vulnerability
  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Remediation status

    No fixed release is recorded for CVE-2026-103367 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.

  3. Mitigate without a patch

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
