CVE-2023-36511Network attack vector

Unauthorized state changes via forged requests

Published Jul 17, 2023 · Updated Apr 28, 2026

Cross-site request forgery in WooCommerce Order Barcodes 1.6.4 and earlier allows remote attackers to perform an unauthorized action. Neither the CNA record nor the linked advisory identifies the vulnerable handler or the request-validation operation it performs incorrectly. Exploitation requires interaction from a logged-in user authorized for the affected action, and the CNA assessment limits the reported consequence to a low-integrity change.
