Vulnerability in Frappe ERPNext

[ Description ]Official description

Frappe ERPNext versions before 16.34.1 fail to validate that Financial Report Template calculation_formula values reference whitelisted methods before passing them to frappe.call(). Accounts Managers can supply arbitrary dotted Python paths to invoke non-whitelisted internal server-side methods and read their return values.
