Unauthorized action via missing nonce validation
Published Dec 18, 2023 · Updated Apr 28, 2026
CSRF in WooCommerce Canada Post Shipping Method 2.8.3 and earlier allows remote attackers to invoke an action via a forged request. An unspecified plugin function accepts requests without correct WordPress nonce validation, so it cannot verify that the administrator intended the action. Exploitation requires an authenticated site administrator to load attacker-controlled content; the published record limits the consequence to unauthorized data modification and does not identify the affected action.
