At a glance

CVE-2026-1787 is a medium-severity Missing Authorization vulnerability in the LearnPress WordPress plugin, affecting versions <= 4.1.0. It carries a CVSS score of 4.8 (reachable over the network). Exploitation requires no authentication. The issue is fixed in version 4.1.1; sites on affected versions should update now. Disclosed February 2026, reported by Osvaldo Noe Gonzalez Del Rio (Os).

Vulnerability Overview

The LearnPress Export Import – WordPress extension for LearnPress plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'delete_migrated_data' function in all versions up to, and including, 4.1.0. This makes it possible for unauthenticated attackers to delete course that have been migrated from Tutor LMS. The Tutor LMS plugin must be installed and activated in order to exploit the vulnerability.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user.

CWE-862: Missing Authorization

LearnPress <= 4.1.0 carries this weakness at delete_migrated_data, and reaching it takes no account at all. 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 LearnPress the fix is 4.1.1: builds <= 4.1.0 are affected, anything from 4.1.1 onward is not.

Remediation

Update to version 4.1.1, or a newer patched version

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. None of that substitutes for the fix: LearnPress 4.1.1 closes this, and updating the plugin is the step that ends it.
