CVE-2026-93580: CWE-862 Missing Authorization in InPost PL
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.
AI Analysis
Technical Summary
CVE-2026-93580 describes a missing authorization vulnerability (CWE-862) in the InPost PL WordPress plugin before version 1.9.8. The plugin does not properly authenticate shipment webhook requests, relying solely on a non-secret identifier and an IP check that is not enforced. Attackers who know a target order's parcel tracking number can exploit this to forge shipment status updates and mark orders as completed without authorization.
Potential Impact
An attacker can manipulate shipment status updates by forging webhook requests, potentially causing orders to be marked as completed prematurely. This could disrupt order processing and fulfillment workflows, leading to operational issues or potential financial impacts. There is no indication of remote code execution or data disclosure beyond order status manipulation.
Mitigation Recommendations
Upgrade the InPost PL plugin to version 1.9.8 or later, where this authorization issue is fixed. Since no official patch links are provided, confirm the availability of the fix with the vendor or plugin repository before upgrading. Do not rely on the plugin's existing IP check or non-secret identifiers for authentication.
