Arkon through 0.9.2 contains a broken access control vulnerability that allows authenticated employees to read and modify other departments' sources because by-id routes in app/routers/sources.py skip can_access_document. Attackers can call the plan, progress, PATCH, retry and approve-extraction routes with foreign source IDs to disclose derived wiki titles and summaries and alter ingestion state.
