Overview

CVE-2026-8502 is a medium-severity vulnerability. It was published on June 6, 2026 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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, 4.3.6 via the 'return_type' parameter. This makes it possible for unauthenticated attackers to extract sensitive data including the plaintext post_password of password-protected courses and the full post_content, post_author, and post_name of unpublished draft, private, and pending courses via the unrestricted SELECT * fallback query. Exploitation requires supplying both c_status=all (to bypass the publish-only post_status WHERE clause) and return_type=json (to prevent the safe DISTINCT(ID) AS ID field override) in a single unauthenticated request to the /wp-json/lp/v1/courses/archive-course endpoint.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
