CVE-2025-48373Network attack vector

Unauthorized panel access via client-side role trust

Published May 22, 2025 · Updated May 27, 2025

Incorrect authorization in schule111 Schule before 1.0.1 allows remote attackers to access restricted panels by altering client-side role data. The index.js login handler trusts the response data.role value and redirects directly to a matching role panel instead of requiring a server-side role decision. No prior privileges are required; successful manipulation grants access to role-restricted application areas, including the admin panel.
