2DescriptionCVE.org
The CorvusPay WooCommerce Payment Gateway plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.7.4. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to cancel any WooCommerce order placed via the CorvusPay payment method by supplying an arbitrary order number to the /wp-json/corvuspay/cancel/ REST endpoint.
AnalysisAI
Unauthenticated order cancellation in CorvusPay WooCommerce Payment Gateway (all versions up to and including 2.7.4) allows any remote attacker to cancel any WooCommerce order paid via CorvusPay by supplying an arbitrary order number to the /wp-json/corvuspay/cancel/ REST API endpoint. The plugin registers this cancel endpoint without implementing a WordPress permission callback, meaning no authorization is verified before processing cancellation requests (CWE-862). …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target WordPress site has the CorvusPay WooCommerce Payment Gateway plugin installed, active, and at version 2.7.4 or earlier, and that at least one order has been placed using the CorvusPay payment method. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.3 Medium score with vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N accurately reflects the technical characteristics: fully network-accessible, no complexity barrier, and no authentication required. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sends unauthenticated HTTP requests to the target WooCommerce store's /wp-json/corvuspay/cancel/ endpoint, iterating sequential integer order IDs. For each valid CorvusPay-paid order, the plugin processes the cancellation without verifying the requester's identity or ownership. … |
