Technical details

The GET /manage/getLibRawFileOnePage endpoint lacks authentication checks, allowing unauthenticated access to retrieve PDF-rendered document pages. Attackers can enumerate sequential admin_user_id and file_id parameters to bypass ownership checks and access any tenant's knowledge-base documents across the multi-tenant platform. No authentication or authorization validation is performed before returning sensitive document content.
