CVE-2026-13329

Name of the Vulnerable Software and Affected Versions Buckaroo Woocommerce Payments Plugin versions prior to 4.9.0

Description An issue exists where the plugin fails to perform capability checks or nonce validation—a security mechanism used to prevent cross-site request forgery—on an AJAX action used to process payment capture refunds.
