## Technical details

An Insecure Direct Object Reference (IDOR) vulnerability exists in ClassroomIO version 0.1.13 due to improper authorization checks on sensitive course management endpoints. An attacker, typically authenticated as a student or low-privileged user, can bypass intended access controls by directly navigating to specific URLs such as /courses/{course-id}/settings#share and /courses/{course-id}/people?add=true. By supplying a valid course ID, the attacker gains access to the Share and Invite management interfaces, allowing them to manipulate course settings and user invitations. The vulnerability is classified under CWE-639 (Authorization Bypass Through User-Controlled Key).
