TL;DR

The web UI does not limit the size of request bodies on POST, PUT, or PATCH. A remote attacker can send an oversized body to these endpoints, causing the server to buffer unbounded data and leading to high memory use or denial of service. The fix adds a middleware that wraps the request body with http.MaxBytesReader (1MB limit) for those methods.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.
