It carries a CVSS score of 7.3 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview
The Abandoned Cart Pro for WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 10.4.0. This is due to insufficient restriction on the capabilities a user may grant themselves. This makes it possible for unauthenticated attackers to elevate their privileges beyond those intended for their role.
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 privileges on the target site, and no interaction from a victim user.
CWE-269: Improper Privilege Management
Reaching this weakness in Abandoned Cart Pro for WooCommerce <= 10.4.0 takes no account at all. 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. No fixed build of this plugin is recorded for Abandoned Cart Pro for WooCommerce yet, so installs running <= 10.4.0 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
