WordPress Plugin Vulnerabilities

InPost for WooCommerce 1.7.5 - 1.9.7 - Unauthenticated Order Status Forgery via Shipment Webhook

Description

The plugin does not verify the authenticity of incoming shipment webhook requests, relying only on a non-secret identifier and an IP check that is not enforced, allowing unauthenticated attackers who know a target order's parcel tracking number to forge its shipment status and prematurely mark the order completed.
