Attackers can invoke single or bulk deletion requests with arbitrary invoice identifiers to delete invoices they do not own, resulting in unauthorized data loss.","summary":"Munshi by Petpooja, a hosted invoice/accounting product, lets an authenticated sub-user delete invoices owned by the tenant owner through DELETE /api/invoice/{invoice_id} and POST /api/invoices/bulk-delete.
