At a glance

CVE-2020-11511 is a high-severity Improper Privilege Management vulnerability in the LearnPress WordPress plugin, affecting versions <= 3.2.6.8. It carries a CVSS score of 8.1 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.2.6.9; sites on affected versions should update now. Disclosed April 2020, reported by Ram.

Vulnerability Overview

The LearnPress plugin before 3.2.6.9 for WordPress allows remote attackers to escalate the privileges of any user to LP Instructor via the accept-to-be-teacher action parameter.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-269: Improper Privilege Management

Reaching this weakness in LearnPress <= 3.2.6.8 takes a caller who can reach the endpoint. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For LearnPress the fix is 3.2.6.9: builds <= 3.2.6.8 are affected, anything from 3.2.6.9 onward is not.

Remediation

Update to version 3.2.6.9, 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: LearnPress 3.2.6.9 closes this, and updating the plugin is the step that ends it.
