Summary

PlayEdu through 2.3 contains a missing authorization flaw in its CourseController (CWE-639). The course endpoints omit the department visibility check, so authenticated students can open courses restricted to other departments. A remote attacker with a student account can enumerate sequential course and attachment IDs to obtain course structure and attachment files from other departments.
