What is CVE-2026-127207?

The Sendcloud for WooCommerce plugin version 1.0.41 has a missing authorization vulnerability that allows authenticated low-privileged users, such as Subscribers, to exploit AJAX actions (sc_support_get and sc_support_save) without adequate capability checks. This can be done directly or through cross-site request forgery, leading to exposure of sensitive integration configuration data like INTEGRATION_ID, SERVICE_POINT, and CARRIERS, as well as the ability to modify logging verbosity. This vulnerability is an incomplete fix of a prior issue (CVE-2026-57760) and poses significant risks if not addressed.

Affected Version(s)

Sendcloud for WooCommerce: Automated Shipping, Branded Tracking & Returns 0 <= 1.0.41
