CVE-2026-93580: InPost for WooCommerce 1.7.5 - 1.9.7 - Unauthenticated Order Status Forgery via Shipment Webhook
- Severity: medium (CVSS 5.3 v3.1)
- Exploited in the wild: not listed in CISA KEV

- Public exploit or detection template: none known
- Published: 2026-09-30 · updated 2026-09-30
- Weakness: CWE-862
Description
The InPost PL WordPress plugin before 1.9.8 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.
Affected products
- InPost PL: from 1.7.5 before 1.9.8 — fixed in 1.9.8
How to fix
Upgrade to a fixed version: InPost PL 1.9.8. Check the vendor advisory for mitigations.
