The PHP SDK documents Composer, mbstring and API-key Shipment operations and states that only the latest major release receives bug and security fixes.

Scope: These sources establish a customer-side PHP integration. Provider infrastructure impact or remediation for PHP2Shell (CVE-2026-109618 / CVE-2026-109619) remains unverified. SDK availability or minimum PHP requirements are not proof of remediation.

What users should do

Check the installed major version and mbstring and test shipping and labels with test credentials, keeping production purchases separate.
