CVE-2023-4161Network attack vector

Invoice-field creation via missing nonce check

Published Aug 31, 2023 · Updated Apr 8, 2026

Cross-site request forgery in EDGARROJAS PDF Builder for WooCommerce 1.2.90 and earlier allows remote attackers to create invoice fields. The SaveCustomField function accepts a state-changing request without validating a WordPress nonce before creating a custom invoice field. Exploitation requires an authenticated administrator to follow an attacker-controlled link or submit a crafted request, and the resulting change is limited to invoice-field creation.
