CVE-2024-6099 is a medium-severity Unprotected Alternate Channel vulnerability in the LearnPress WordPress plugin, affecting versions <= 4.2.6.8.1. 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 4.2.6.8.2; sites on affected versions should update now. Disclosed July 2024, reported by shaman0x01.

Vulnerability Overview

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to unauthenticated bypass to user registration in versions up to, and including, 4.2.6.8.1. This is due to missing checks in the 'check_validate_fields' function in the checkout. This makes it possible for unauthenticated attackers to register as the default role on the site, even if registration is disabled.

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-420: Unprotected Alternate Channel

The product protects a primary channel, but it does not use the same level of protection for an alternate channel.

Remediation

Update to version 4.2.6.8.2, 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 4.2.6.8.2 closes this, and updating the plugin is the step that ends it.
