CVE-2026-93580
MediumCVSS 5.3Summary
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.
Risk Assessment
Attackers can manipulate order statuses, potentially leading to fraudulent order fulfillment, financial losses, and loss of customer trust.
Recommendation
Update the InPost PL plugin to version 1.9.8 or later and implement strong webhook authentication, such as request signing.
