CVE-2025-62393 is a vulnerability identified in version 5.0.0 of a software product involving improper enforcement of access control in the course overview output function. Specifically, the flaw allows users with some level of privileges (PR:L) to bypass intended access restrictions and view course information that should be restricted. The vulnerability affects confidentiality by exposing limited course details to unauthorized users but does not affect data integrity or system availability. The CVSS 3.1 base score is 4.3, reflecting a network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and limited confidentiality impact (C:L). No known exploits have been reported in the wild, and no official patches are currently linked, although the vulnerability was published on October 23, 2025. The flaw likely stems from insufficient validation or enforcement of user permissions when generating or delivering course overview data, which could be exploited by authenticated users to gain unauthorized read access. This vulnerability is particularly relevant for educational platforms or learning management systems that handle sensitive course information and user access roles.

For European organizations, especially educational institutions, e-learning providers, and corporate training platforms, this vulnerability poses a confidentiality risk by potentially exposing course content or metadata to unauthorized users. While the impact on integrity and availability is negligible, unauthorized disclosure of course details could lead to privacy violations, intellectual property exposure, or competitive disadvantages. Organizations relying on the affected software version 5.0.0 may face compliance challenges under GDPR if personal or sensitive data is exposed. The risk is heightened in environments where user roles are not strictly segregated or where multiple users share similar privilege levels. Although no active exploitation is known, the ease of exploitation due to low complexity and network accessibility means attackers with legitimate access could leverage this flaw to gather unauthorized information. This could facilitate further social engineering or targeted attacks within educational or corporate environments.

Organizations should immediately audit their deployment of the affected software and verify if version 5.0.0 is in use. Until an official patch is released, administrators should implement strict role-based access controls, ensuring that users have the minimum necessary privileges to access course data. Review and harden access control policies around course overview functions, possibly disabling or restricting access to sensitive course metadata for lower-privileged users. Implement monitoring and logging of access to course overview data to detect anomalous access patterns indicative of exploitation attempts. Educate users about the risk of unauthorized data access and encourage reporting of suspicious behavior. Once patches or updates become available from the vendor, prioritize their deployment. Additionally, consider network segmentation or application-layer firewalls to limit exposure of the vulnerable service to trusted users only. Regularly review and update user permissions to prevent privilege creep.
