Risk Assessment
An attacker can access sensitive files, compromising data confidentiality and potentially leading to leakage of research information.
Recommendation
Upgrade to version 27.0.3 or 28.0.1, which include a fix for this vulnerability.
Original NVD description (English source)
LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. From 16.1.0 to before 27.0.3 and 28.0.1, While the frontend of the media module filters files that the user should not have access to, the backend was not applying access checks and it would be possible for someone who should not have access to a file to access it if they know the filename. This vulnerability is fixed in 27.0.3 and 28.0.1.
