At a glance
CVE-2026-1748 is a medium-severity Missing Authorization vulnerability in the Invoct WordPress plugin, affecting versions <= 1.6. 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 1.7; sites on affected versions should update now. Disclosed February 2026, reported by Teerachai Somprasong.
Vulnerability Overview
The Invoct – PDF Invoices & Billing for WooCommerce plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on multiple functions in all versions up to, and including, 1.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve invoice clients, invoice items, and list of WordPress users along with their emails.
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
Reaching this weakness in Invoct <= 1.6 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 Invoct the fix is 1.7: builds <= 1.6 are affected, anything from 1.7 onward is not.
Remediation
Update to version 1.7, 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: Invoct 1.7 closes this, and updating the plugin is the step that ends it.
