# Arkon: wiki graph endpoint leaks other departments' page metadata to employees

Arkon through 0.9.2 lacks an authorization check on GET /api/wiki/graph, so an authenticated employee can pass a foreign slug. The response exposes wiki page slugs, titles, types and link edges from other departments up to depth 3.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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.
