At a glance
CVE-2026-48873 is a medium-severity Missing Authorization vulnerability in the Montonio for WooCommerce WordPress plugin, affecting versions <= 10.1.2. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 10.1.3; sites on affected versions should update now. Disclosed June 2026, reported by Niv Kochan.
Vulnerability Overview
The Montonio for WooCommerce plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in versions up to, and including, 10.1.2. This makes it possible for unauthenticated attackers to perform an unauthorized action.
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-862: Missing Authorization
Reaching this weakness in Montonio for WooCommerce <= 10.1.2 takes a caller who can reach the endpoint. 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 Montonio for WooCommerce the fix is 10.1.3: builds <= 10.1.2 are affected, anything from 10.1.3 onward is not.
Remediation
Update to version 10.1.3, 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: Montonio for WooCommerce 10.1.3 closes this, and updating the plugin is the step that ends it.
