CVE-2025-11280 is a medium-severity vulnerability identified in Frappe LMS version 2.35.0, specifically within the Assignment Picture Handler component located in the /files/ directory. The vulnerability allows for a 'direct request' manipulation, which implies that an attacker can directly interact with a resource or function in an unintended manner. The flaw is remotely exploitable without requiring authentication or user interaction, but the attack complexity is rated as high and exploitability is considered difficult. This suggests that while the vulnerability can be triggered remotely, it requires significant skill or specific conditions to successfully exploit. The CVSS 4.0 vector (AV:N/AC:H/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P) indicates network attack vector, high attack complexity, no privileges or user interaction needed, and partial impact on confidentiality (low), with no impact on integrity or availability. The vendor was notified early about four security issues, including this one, and claims to have fixed them, though the release notes on GitHub do not explicitly mention these fixes. No official patch links are provided, and no known exploits are currently observed in the wild. The vulnerability likely allows unauthorized access to certain assignment picture resources or functions, potentially exposing sensitive educational content or user data, but without broader system compromise or service disruption.

For European organizations using Frappe LMS 2.35.0, this vulnerability poses a risk of unauthorized access to assignment-related files or data, which could lead to leakage of sensitive educational materials or personal information of students and staff. While the impact on confidentiality is low and no integrity or availability impacts are noted, the exposure of educational content could violate data protection regulations such as GDPR, leading to reputational damage and potential regulatory penalties. The high attack complexity and lack of known exploits reduce immediate risk, but the presence of a public exploit means motivated attackers could eventually leverage this vulnerability. Educational institutions, training providers, and organizations relying on Frappe LMS for learning management in Europe should be aware of this risk, especially those handling sensitive or regulated data.

European organizations should prioritize upgrading Frappe LMS to a version that includes the vendor's security fixes once officially released and documented. In the interim, organizations can implement strict access controls on the /files/ directory and related assignment picture resources to restrict direct URL access only to authorized users. Web application firewalls (WAFs) can be configured to detect and block suspicious direct request patterns targeting the vulnerable component. Monitoring and logging access to assignment picture resources should be enhanced to detect anomalous activity. Additionally, organizations should conduct internal security assessments and penetration tests focusing on the LMS file handling components to identify any exploitation attempts. Communication with the vendor to obtain official patches and detailed remediation guidance is recommended. Finally, educating LMS administrators on secure configuration and timely patching is essential to reduce exposure.
