AI Analysis
Technical Summary
CVE-2026-9028 is an authorization bypass vulnerability (CWE-862) in the CorvusPay WooCommerce Payment Gateway plugin for WordPress. The plugin fails to properly verify that a user is authorized to cancel orders via the /wp-json/corvuspay/cancel/ REST endpoint. As a result, unauthenticated attackers can cancel any order placed using the CorvusPay payment method by supplying an arbitrary order number. This affects all versions up to and including 2.7.4. The CVSS 3.1 base score is 5.3 (medium severity) with vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N, indicating network attack vector, low attack complexity, no privileges or user interaction required, unchanged scope, no confidentiality or availability impact, but integrity impact limited to order cancellation.
Potential Impact
An attacker without authentication can cancel any WooCommerce order paid through CorvusPay by exploiting the authorization bypass. This impacts the integrity of order management but does not affect confidentiality or availability of the system. There is no indication of exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the /wp-json/corvuspay/cancel/ REST endpoint if possible, or disable the CorvusPay payment method temporarily to prevent unauthorized order cancellations.
