CVE-2021-4414Network attack vector

Email preview generation via missing nonce validation

Published Jul 12, 2023 · Updated Apr 8, 2026

Cross-site request forgery in Tyche Softwares Abandoned Cart Lite for WooCommerce 5.8.5 and earlier allows remote attackers to generate email previews. The wcal_preview_emails() handler processes a preview request without validating a WordPress nonce, so it accepts requests forged from another site. Exploitation requires an authenticated site administrator to interact with an attacker-controlled link or page; the bounded effect is generation of preview templates.
