Student access to course administration via unchecked identifiers

Published Nov 26, 2025 · Updated Jul 5, 2026

IDOR in course settings in ClassroomIO 0.1.13 allows remote authenticated users to access restricted sharing and invite controls. The share and people routes accept a user-controlled course ID and expose administrator-only interfaces without verifying course ownership or role. A student account and a known course ID are required; successful exploitation exposes course sharing and invite management to the student.
