Yao through v1.0.0-rc22 authenticates but fails to authorize the GET /user/teams/:id endpoint, allowing any logged-in user to read full team records. Attackers can supply a known team identifier to retrieve sensitive team data including name, description, owner information, and settings without membership verification.
