CVE-2025-11281 identifies an improper access control vulnerability in Frappe LMS version 2.35.0, specifically within the /courses/ directory handling unpublished courses. The vulnerability arises from insufficient enforcement of access restrictions on unpublished course content, allowing remote attackers to bypass intended access controls and potentially view or interact with course materials that should remain private. The attack vector is network-based (AV:N), and exploitation requires high complexity (AC:H), indicating that an attacker must overcome significant technical challenges to succeed. No user interaction (UI:N) or authentication (PR:L) is required, but some limited privileges may be necessary. The vulnerability impacts confidentiality, integrity, and availability at a low level (VC:L, VI:L, VA:L). Although the vendor was informed early about this and three other issues, the fixes are not clearly documented in the public release notes, which may delay awareness and patching. No known exploits are currently active in the wild, but public disclosure increases the risk of future exploitation. Organizations running this specific version of Frappe LMS should prioritize upgrading to a patched version once available or apply recommended mitigations to prevent unauthorized access to unpublished course data.

For European organizations, particularly educational institutions and training providers using Frappe LMS 2.35.0, this vulnerability could lead to unauthorized disclosure of unpublished course content, potentially exposing sensitive educational materials or intellectual property. Although the overall severity is low, the breach of confidentiality could undermine trust, violate data protection regulations such as GDPR if personal data is involved, and disrupt course management workflows. The limited exploitability reduces immediate risk, but the public disclosure means attackers may develop exploits over time. Organizations relying on Frappe LMS for critical training or compliance purposes may face reputational damage or operational challenges if unauthorized access occurs. The impact on integrity and availability is minimal, but confidentiality concerns warrant attention, especially in regulated environments.

European organizations should immediately verify if they are running Frappe LMS version 2.35.0 and plan to upgrade to the latest patched release once available. In the absence of an official patch, administrators should restrict network access to the LMS, especially the /courses/ endpoint, using firewalls or web application firewalls (WAFs) to limit exposure. Implement strict role-based access controls (RBAC) within the LMS to ensure only authorized users can access unpublished courses. Conduct thorough access audits and monitor LMS logs for unusual access patterns targeting unpublished content. Engage with the vendor or community to confirm patch availability and track updates. Additionally, consider isolating the LMS environment and applying network segmentation to reduce attack surface. Educate LMS administrators on the importance of timely updates and secure configuration management to prevent exploitation of similar vulnerabilities.
