At a glance
CVE-2026-8615 is a medium-severity Missing Authorization vulnerability in the ilGhera Reviso Exporter for WooCommerce WordPress plugin, affecting versions <= 1.2.3. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 1.2.4; sites on affected versions should update now. Disclosed September 2026, reported by Legion Hunter.
Vulnerability Overview
The Reviso Exporter for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check and missing nonce verification on the disconnect_callback() function in versions up to, and including, 1.2.3. The function is registered to the 'wp_ajax_wcefr-disconnect' AJAX action and unconditionally calls delete_option('wcefr-agt'), which removes the Reviso Agreement Grant Token used to authenticate API calls. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete the plugin's stored Agreement Grant Token, breaking the connection between WooCommerce and the Reviso service.
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.
CWE-862: Missing Authorization
ilGhera Reviso Exporter for WooCommerce <= 1.2.3 carries this weakness at wp_ajax_wcefr-disconnect, and reaching it takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For ilGhera Reviso Exporter for WooCommerce the fix is 1.2.4: builds <= 1.2.3 are affected, anything from 1.2.4 onward is not.
Remediation
Update to version 1.2.4, 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: ilGhera Reviso Exporter for WooCommerce 1.2.4 closes this, and updating the plugin is the step that ends it.
