CVE-2025-11368 in LearnPress Plugin
Summary
by MITRE • 11/21/2025
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/load_content_via_ajax 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 vulnerability CVE-2025-11368 affects the LearnPress WordPress LMS plugin, specifically targeting versions up to and including 4.2.9.4. This issue represents a critical security flaw that undermines the confidentiality of educational content within WordPress environments. The vulnerability stems from inadequate access control mechanisms within the plugin's REST API implementation, creating a pathway for unauthorized information disclosure that directly impacts the security posture of learning management systems deployed on WordPress platforms.
The technical flaw manifests in the /wp-json/lp/v1/load_content_via_ajax REST endpoint which lacks proper capability checks and authentication validation. This endpoint is designed to handle AJAX requests for loading educational content but fails to verify whether the requesting user possesses appropriate administrative privileges. The vulnerability allows for arbitrary callback execution of admin-only template methods, effectively bypassing the intended access controls that should restrict sensitive content retrieval to authorized administrators only. The flaw operates through a predictable pattern where attackers can supply valid numeric IDs to access protected content, making the exploitation straightforward and automated.
The operational impact of this vulnerability is severe for educational institutions and organizations using LearnPress as their primary learning management system. Unauthenticated attackers can systematically retrieve sensitive educational materials including admin curriculum HTML, quiz questions with correct answers, and course materials that would typically be restricted to authorized users. This information disclosure creates significant risks for academic integrity, as test questions and answers become accessible to unauthorized parties. The vulnerability undermines the fundamental security assumptions of the platform, potentially exposing proprietary educational content, assessment materials, and administrative configurations that could be exploited for competitive advantage or malicious purposes.
This vulnerability aligns with CWE-284 (Improper Access Control) and represents a classic example of insufficient privilege checking in web applications. The flaw also maps to ATT&CK technique T1213.002 (Data from Cloud Storage) and T1005 (Data from Local Storage) as it enables unauthorized access to stored educational content and administrative data. Organizations should immediately implement mitigations including patching to the latest plugin versions, implementing additional access controls through WordPress security plugins, and monitoring REST API access patterns for suspicious activity. Network-level restrictions on the affected REST endpoints can serve as temporary protective measures while permanent fixes are deployed, ensuring that only authenticated administrative users can access sensitive educational content through the API.
The broader implications extend beyond immediate information disclosure, as this vulnerability demonstrates the critical importance of proper access control implementation in web applications. Educational institutions must recognize that learning management systems contain sensitive data that requires robust protection mechanisms. The vulnerability highlights the need for comprehensive security testing of third-party plugins, particularly those handling educational content and user data. Organizations should conduct regular security assessments of their WordPress environments and implement security monitoring solutions to detect unauthorized access attempts to REST API endpoints. The incident serves as a reminder that even seemingly routine plugin functionality can introduce critical security risks when proper access control mechanisms are absent or insufficiently implemented.
