Partial Shipment for WooCommerce · Vulnerability

CVSS 3.1 4.3 MEDIUMCheck source for fixed versionsKEV status unknown

cve-program · CVE-2026-9858

Published

The Partial Shipment for Woocommerce plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 3.4 via the wxp_order_shipment, wxp_order_item_shipment, and wxp_order_set_shipped AJAX actions. This is due to the AJAX handlers in woocommerce-partial-shipment.php (registered at lines 60–62 and implemented at lines 228, 263, and 291) lacking both capability checks and nonce verification, and not validating the calling user's ownership of the supplied order_id. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read arbitrary order item details (names, quantities, shipped counts) belonging to any customer and to modify the shipment status / shipped quantities of any order, which can also trigger order status transitions via the wxp_order_status action.

Affected versions, risk and source history

Exploitation and risk

Source status

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Risk history

Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.

When does an EPSS score appear as a change?

A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.

Advisory history

1 saved versions

See how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.

How advisory history works

Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
