Detailed vulnerability description

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled recursion in toFormData in lib/helpers/toFormData.js when processing deeply nested request data or params objects. A remote attacker can send a deeply nested object to cause a denial of service.

The issue can be reached in server-side code that forwards client-controlled objects into axios request data or params, and may terminate the running request handler or process with a RangeError.
