CVE-2025-65670
An Insecure Direct Object Reference (IDOR) in classroomio 0.1.13 allows students to access sensitive admin/teacher endpoints by manipulating course IDs in URLs, resulting in unauthorized disclosure of sensitive course, admin, and student data.
Does this matter?
Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.
