Forged read-only actions via missing nonce checks

Published Jul 1, 2023 · Updated Apr 8, 2026

CSRF in VillaTheme Abandoned Cart Recovery for WooCommerce 1.0.4 and earlier allows remote attackers to trigger read-only actions. The get_items() and extra_tablenav() functions omit or incorrectly perform WordPress nonce validation before processing requests. Exploitation requires an administrator to follow a forged link or perform an equivalent attacker-induced action, and the documented consequence is limited to read-only operations.
