Summary
LearnHouse before 1.1.1 contains a missing authorization vulnerability in the assignment API that allows authenticated users to read other users' grades and submissions. Attackers can supply another user_id to the submissions grade endpoint or query submission read functions to view other students' work, grades and instructor feedback.
