CVE-2025-11281 is a security vulnerability identified in Frappe LMS version 2.35.0, specifically within an unknown function related to the /courses/ component, known as the Unpublished Course Handler. The vulnerability arises from improper access controls, which could allow an attacker to remotely manipulate access permissions to unpublished course content or related resources. The attack vector is network-based (AV:N), requiring no user interaction (UI:N) and no privileges (PR:L) beyond limited privileges, but it is characterized by high complexity (AC:H), making exploitation difficult. The vulnerability impacts confidentiality, integrity, and availability to a limited extent (VC:L, VI:L, VA:L). Although the vendor was informed early about this and three other security issues, the official release notes on GitHub do not mention these fixes, potentially leaving users unaware of the need to upgrade. The CVSS 4.0 base score is 2.3, indicating a low severity level. No known exploits are currently in the wild, and no patches or mitigation links have been provided publicly. The vulnerability's existence in a learning management system (LMS) could allow unauthorized access to unpublished educational content, potentially exposing sensitive academic materials or allowing unauthorized modifications. However, the difficulty of exploitation and limited impact reduce the immediate risk level.

For European organizations, particularly educational institutions and training providers using Frappe LMS 2.35.0, this vulnerability could lead to unauthorized disclosure or modification of unpublished course content. This may affect the confidentiality of proprietary educational materials or intellectual property, and could undermine the integrity of course offerings. While the impact on availability is limited, unauthorized access could disrupt course management workflows or lead to reputational damage if sensitive content is leaked. Given the low CVSS score and high complexity of exploitation, the immediate risk is low; however, the presence of publicly disclosed details without official patches increases the risk over time, especially if attackers develop reliable exploits. European organizations with strict data protection regulations (e.g., GDPR) must consider the potential for data exposure and ensure compliance by addressing this vulnerability promptly.

1. Upgrade Frappe LMS to the latest version once the vendor officially releases patches addressing CVE-2025-11281 and related vulnerabilities. 2. Until patches are available, implement strict network segmentation and access controls to limit exposure of the LMS to trusted users and networks only. 3. Monitor LMS logs for unusual access patterns or attempts to access unpublished course content. 4. Conduct internal audits of user privileges to ensure minimal necessary access rights, reducing the risk posed by low-privilege exploitation. 5. Engage with the Frappe community or vendor support channels to obtain unofficial patches or workarounds if official updates are delayed. 6. Educate LMS administrators about the vulnerability and encourage prompt application of security updates. 7. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the /courses/ endpoint.
