CVE-2025-11554 is a security vulnerability identified in the Portabilis i-Educar platform, specifically affecting versions 2.9.0 through 2.9.10. The issue resides in the User Type Handler component, within the file app/Http/Controllers/AccessLevelController.php, where insecure inherited permissions are improperly managed. This flaw allows remote attackers to manipulate permission inheritance mechanisms without requiring authentication or user interaction, potentially leading to unauthorized privilege escalation or access to restricted functionalities. The vulnerability is exploitable over the network with low complexity, as indicated by the CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N). Although the attack requires some level of privileges (PR:L), it does not require user interaction, and the impact affects confidentiality, integrity, and availability at a limited level. The vulnerability has been publicly disclosed, increasing the risk of exploitation despite no known active exploits in the wild. The insecure permission inheritance could allow attackers to gain elevated access rights within the i-Educar system, compromising sensitive educational data or administrative controls. The lack of available patches at the time of disclosure necessitates immediate attention to access control policies and monitoring. Given i-Educar’s role in managing educational environments, exploitation could disrupt school operations and expose personal data of students and staff.

For European organizations, particularly educational institutions using Portabilis i-Educar, this vulnerability poses a risk of unauthorized access and privilege escalation within their administrative systems. Exploitation could lead to exposure or modification of sensitive student and staff data, disruption of educational services, and potential compliance violations under GDPR due to data breaches. The medium severity score reflects moderate impact, but the ease of remote exploitation without user interaction increases urgency. Organizations relying on i-Educar for school management may face operational disruptions and reputational damage if attackers leverage this flaw. The vulnerability could also be leveraged as a foothold for further attacks within the network, especially in environments with weak internal segmentation. Given the public disclosure, threat actors may develop exploits targeting European schools, which often have limited cybersecurity resources. The impact extends beyond confidentiality to integrity and availability of educational data and services, potentially affecting large numbers of students and staff.

Immediate mitigation should focus on restricting access to the i-Educar management interfaces, especially the AccessLevelController functionality, through network segmentation and firewall rules limiting access to trusted administrators only. Organizations should enforce the principle of least privilege rigorously, reviewing and tightening user roles and permissions within i-Educar to minimize the risk of privilege escalation. Monitoring and logging of permission changes and access attempts should be enhanced to detect suspicious activities promptly. Until official patches are released by Portabilis, consider deploying web application firewalls (WAFs) with custom rules to block anomalous requests targeting the vulnerable controller. Conduct thorough audits of current permission inheritance configurations to identify and remediate insecure settings. Educate administrative users about the risk and encourage prompt reporting of unusual system behavior. Once patches become available, prioritize their deployment in all affected environments. Additionally, implement multi-factor authentication for administrative access to reduce the risk of credential compromise.
