At a glance
CVE-2026-81543 is a high-severity Improper Privilege Management vulnerability in the Abandoned Cart Pro for WooCommerce WordPress plugin, affecting versions <= 10.7.1. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 10.7.2; sites on affected versions should update now. Disclosed September 2026, reported by d.v4n_s3c.
Vulnerability Overview
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.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-269: Improper Privilege Management
Reaching this weakness in Abandoned Cart Pro for WooCommerce <= 10.7.1 takes an account at Subscriber level or above. Improper privilege management means the code lets an account end up with capabilities its role should not have.
It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Abandoned Cart Pro for WooCommerce the fix is 10.7.2: builds <= 10.7.1 are affected, anything from 10.7.2 onward is not.
Remediation
Update to version 10.7.2, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Abandoned Cart Pro for WooCommerce 10.7.2 closes this, and updating the plugin is the step that ends it.
