What is CVE-2026-81427?

The WC Vendors plugin for WordPress prior to version 2.7.2.1 contains a significant authorization flaw. This security issue allows any authenticated vendor to modify the shipment status of orders they do not own. As a result, they can mark orders as shipped, which misrepresents their involvement and sends misleading notifications to customers. This vulnerability poses a risk to the integrity of order management and can lead to customer confusion, impacting trust and operational credibility. Website owners using this plugin should update to the latest version to mitigate these risks.

Affected Version(s)

WC Vendors 0 < 2.7.2.1
