## Technical details

The GET /api/wiki/graph endpoint fails to validate authorization scope when calling get_neighborhood(), allowing authenticated users with wiki:read:own_dept permission to query arbitrary page slugs and traverse up to depth 3 in the wiki link graph. An attacker can enumerate page structure, titles, types, and relationships across departments without proper access checks.
