The Fast Courier WordPress plugin through 5.2.3 does not restrict an unauthenticated REST route that writes order fulfillment data, allowing unauthenticated attackers to overwrite the courier status and customer-facing tracking details of any WooCommerce order by supplying its id.
AnalysisAI
Order tampering in the Fast Courier WordPress plugin (versions through 5.2.3) lets unauthenticated attackers overwrite the courier status and customer-facing tracking details of any WooCommerce order by supplying the target order's ID to an unprotected REST route. The underlying defect is a missing authorization check (CWE-862) on the plugin's order-fulfillment endpoint, so remote attackers need no credentials and no user interaction (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N, score 5.3); the practical prerequisite is knowing or enumerating a valid WooCommerce order ID. …

Vulnerability AssessmentAI
| Exploitation | Exploitable only against WordPress sites running the Fast Courier plugin (version ≤5.2.3) with WooCommerce active, via the plugin's unauthenticated order-fulfillment REST route - no login, credentials, or user interaction required (PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are consistent and point to a genuine but moderate-severity access-control flaw rather than a critical emergency. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis, and the EUVD data lists all versions through 5.2.3 as affected, so there is currently no fixed version to upgrade to; administrators should monitor the WPScan advisory (https://wpscan.com/vulnerability/716b6d58-a816-43f2-8a1a-b9fe4f2f9d1d/) and the plugin's WordPress.org page for a patched release. … Detailed patch versions, workarounds, and compensating controls in full report. |
