At a glance

CVE-2026-3225 is a medium-severity Missing Authorization vulnerability in the LearnPress WordPress plugin, affecting versions <= 4.3.2.8. 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 4.3.3; sites on affected versions should update now. Disclosed March 2026, reported by AlexHenry.

Vulnerability Overview

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to unauthorized deletion of quiz question answers due to a missing capability check in the delete_question_answer() function of the EditQuestionAjax class in all versions up to, and including, 4.3.2.8. The AbstractAjax::catch_lp_ajax() dispatcher verifies a wp_rest nonce but performs no current_user_can() check, and the QuestionAnswerModel::delete() method only validates minimum answer counts without checking user capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete answer options from any quiz question on the site.

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

LearnPress <= 4.3.2.8 carries this weakness at delete_question_answer(), and reaching it 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 LearnPress the fix is 4.3.3: builds <= 4.3.2.8 are affected, anything from 4.3.3 onward is not.

Remediation

Update to version 4.3.3, 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 4.3.3 closes this, and updating the plugin is the step that ends it.
