Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, an Insecure Direct Object Reference (IDOR) vulnerability in the gradebook result view page allows any authenticated teacher to delete any student's grade result across the entire platform by manipulating the delete_mark or resultdelete GET parameters. No ownership or course-scope verification is performed. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3.
