What is CVE-2026-81543?
CVE-2026-81543 is a high-severity missing authorization vulnerability in Tyche Softwares Abandoned Cart Pro for WooCommerce, published on 5 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The Abandoned Cart Pro for WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 10.7.1. This is due to missing capability checks and nonce verification on multiple AJAX actions including wcap_save_connector_settings, wcap_send_manual_email, wcap_abandoned_cart_info, and wcap_change_manual_email_data. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify SMTP connector settings to route administrator recovery emails through an attacker-controlled server and intercept auto-login links to gain full administrative access. The plugin's auto-login feature must be enabled, which is the default configuration.
Weakness: CWE-269
