Description
Vikunja before 2.7.1 contains an authorization bypass vulnerability that allows authenticated users to read any task by injecting a crafted task object into a no-op Kanban bucket move. Attackers can set task.id to a victim task and task.project_id to their own project, routing full task contents to their webhook and forging mention notifications.
