CVE-2025-30854Network attack vector

Unspecified backend actions via missing nonce validation

Published Mar 27, 2025 · Updated Apr 28, 2026

Cross-site request forgery in Serial Codes Generator and Validator with WooCommerce Support allows remote attackers to trigger backend actions. Backend request handling in 2.7.7 and earlier does not adequately validate a WordPress nonce; public records do not identify the affected action or handler. Exploitation requires an authenticated site user to interact with attacker-controlled content, and the exact unintended state change remains undisclosed.
