At a glance

CVE-2026-8383 is a medium-severity Missing Authorization vulnerability in the LearnPress WordPress plugin, affecting versions <= 4.3.6. 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 4.3.7; sites on affected versions should update now. Disclosed June 2026, reported by dyingman1.

Vulnerability Overview

The LearnPress plugin for WordPress is vulnerable to unauthorized access in versions up to, and including, 4.3.6. This is due to missing validation of the context parameter in the get_items() function of the REST users controller, allowing unauthenticated requests to retrieve sensitive user fields. This makes it possible for unauthenticated attackers to access sensitive user information, including private user data, via the REST API without authentication by supplying a context=edit parameter.

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

LearnPress <= 4.3.6 carries this weakness at get_items(), 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 4.3.7: builds <= 4.3.6 are affected, anything from 4.3.7 onward is not.

Remediation

Update to version 4.3.7, 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 4.3.7 closes this, and updating the plugin is the step that ends it.
