CVE-2026-8383 Scanner

LearnPress is a comprehensive WordPress plugin designed for educational purposes, often utilized by educational institutions and online course providers to create and manage courses. It allows users to design detailed curriculums, manage students, and facilitate online learning with various interactive tools. The plugin integrates seamlessly with WordPress, offering an intuitive interface for course creators and administrators to enhance online education. Regular updates and community support make it a popular choice for educators aiming to deliver effective e-learning experiences. The platform supports numerous add-ons and integrates with popular WordPress themes, making it versatile for different educational needs.

The information disclosure vulnerability in LearnPress allows unauthorized individuals to gain access to sensitive user role and capability data due to insufficient access control checks on the REST API endpoint. This weakness in the API endpoint could potentially lead threat actors to gather information necessary for launching more targeted attacks or escalating privileges. Since it does not require authentication, the issue is considered medium severity, demanding attention to prevent exploitation. Properly securing API endpoints and regularly updating plugins can mitigate the risks associated with this vulnerability. Understanding and patching such vulnerabilities are essential to maintaining the security of WordPress-based e-learning environments.

The technical details of this vulnerability involve inadequate capability checks on a particular REST API endpoint in the LearnPress plugin. An unauthenticated attacker can send crafted requests to the /wp-json/learnpress/v1/users?context=edit endpoint, leading to exposure of sensitive data such as user roles and capabilities. The vulnerability exists in versions prior to 4.3.7, where proper checks were not implemented to restrict access to this data. Successful exploitation involves making a GET request and checking the response for certain elements indicating user role information. Implementing appropriate authorization checks and updating to the latest version can address this gap.

The exploitation of this vulnerability could lead to unauthorized access to confidential information, potentially facilitating further breaches or privilege escalation. Attackers might use the exposed user role data to map out the site's user hierarchy, identifying high-value targets for more focused attacks. Malicious actors can also exploit this information for social engineering attacks, impersonation, or other forms of identity theft. Moreover, knowing user roles and capabilities might help in devising strategies to bypass security controls or gain administrative access improperly. The presence of such vulnerabilities strongly emphasizes the need for layered security measures in plugin and API design.
