## Overview

Kaneo before 2.1.6 contains a missing authorization vulnerability that allows authenticated users to access other workspaces by supplying project, task, label or workspace identifiers to API routes lacking membership checks. Attackers who obtain identifiers, for example from shared project links, can read projects and tasks, modify or delete tasks, labels and comments, and search workspace contents.
