Description
Arkon through 0.9.2 contains a missing authorization vulnerability in GET /api/wiki/graph that lets authenticated employees read other departments' wiki metadata by supplying a foreign slug. Attackers with only wiki:read:own_dept permission can query get_neighborhood() without scope checks to obtain page slugs, titles, types and link edges up to depth 3.
