AI enriched 3 hours ago (2026-11-13 23:42 UTC)

Technical Summary

Sendcloud for WooCommerce through 1.0.41 contains a missing authorization vulnerability that allows authenticated low-privileged users, including Subscribers, to access the sc_support_get and sc_support_save AJAX actions due to the absence of capability and nonce checks in SCCSP_Support_Controller. Attackers can call these wp_ajax_ handlers directly or via cross-site request forgery to disclose integration configuration data such as INTEGRATION_ID, SERVICE_POINT, CARRIERS, and MIN_LOG_LEVEL, and to modify the plugin's logging verbosity. This is an incomplete fix of CVE-2026-57760.
