CVE-2026-9027: CWE-347 Improper Verification of Cryptographic Signature in corvusinfo CorvusPay WooCommerce Payment GatewayCVE-2026-9027
0

The CorvusPay WooCommerce Payment Gateway plugin for WordPress contains a vulnerability in all versions up to and including 2.7.4 that allows unauthenticated attackers to bypass payment verification. This occurs because the plugin's REST endpoint for payment success does not properly verify cryptographic signatures before marking orders as paid. Attackers can exploit this by sending a forged signature in a POST request to the endpoint, causing any pending WooCommerce order to be marked as paid without actual payment. The vulnerability arises from the failure to conditionally check the signature validation result, leading to unconditional order completion.
