The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.4.1 via the checkanswer. This makes it possible for unauthenticated attackers to extract the correct-answer markers, full option lists, explanations, and question content for any quiz question on the site — including questions belonging to paid courses the attacker is not enrolled in.

The LearnPress WordPress plugin before 4.4.1 does not escape a search parameter before reflecting it into an HTML attribute, leading to Reflected Cross-Site Scripting that executes in the browser of a logged-in instructor or administrator who is tricked into opening a crafted link.

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to modification of data in all versions up to, and including, 4.2.9.2. This is due to missing capability checks on the Admin Tools REST endpoints which are registered with permissioncallback set to returntrue. This makes it possible for unauthenticated attackers to perform destructive database operations including dropping indexes on any table (including WordPress core tables like wpoptions), creating duplicate configuration entries, and degrading site performance via the /wp-json/lp/v1/admin/tools/create-indexs endpoint granted they can provide table names.

The LearnPress WordPress plugin before 4.4.4 does not verify that a user is enrolled in a course before processing AI-assistant requests against that course's lesson content, allowing any authenticated user such as a subscriber to obtain material from paid courses they have not enrolled in.

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 4.2.7.5 due to insufficient input sanitization and output escaping of a lesson name. This makes it possible for authenticated attackers, with LP Instructor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to Sensitive Information Disclosure in all versions up to, and including, 4.2.9.4. This is due to missing capability checks in the REST endpoint /wp-json/lp/v1/loadcontentviaajax which allows arbitrary callback execution of admin-only template methods. This makes it possible for unauthenticated attackers to retrieve admin curriculum HTML, quiz questions with correct answers, course materials, and other sensitive educational content via the REST API endpoint granted they can supply valid numeric IDs.

The LearnPress WordPress plugin before 4.0.3 does not perform any authorization check on one of its REST endpoints in all versions up to, and including, 4.0.2, allowing unauthenticated attackers to disclose the payment status of arbitrary orders by enumerating order identifiers.

The LearnPress WordPress plugin before 4.2.7.2 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed (for example in multisite setup).

The LearnPress WordPress plugin before 4.2.7.2 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed (for example in multisite setup).

The LearnPress WordPress plugin before 4.2.7.5.1 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed (for example in multisite setup).

The LearnPress WordPress plugin before 4.2.7.5.1 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed (for example in multisite setup).

The LearnPress plugin for WordPress is vulnerable to unauthorized modification of arbitrary WordPress options in versions up to, and including, 4.4.4 via the learnpresscreatepage AJAX action. The LPAdminAjax::createpage() handler only checks the editpages capability and a wprest nonce (both available to Editors), then reads the fieldname parameter from the request without restricting it to a learnpress allow-list before passing it as the option key to LPHelper::createpage(), which calls updateoption($keyoption, $pageid). This makes it possible for authenticated attackers, with Editor-level access and above, to update arbitrary WordPress options to a positive integer (a newly created page ID), enabling actions such as flipping userscanregister to a truthy value to open public registration, corrupting activeplugins to break the site, or otherwise tampering with site-wide settings normally reserved for administrators.
