Worked on enhancing the security and robustness of the juanfont/headscale repository by implementing a maximum request body size for the Noise Router. Addressed potential unauthenticated out-of-memory risks by introducing a 1 MiB limit using Go’s http.MaxBytesReader, ensuring resource-based attacks are mitigated at the boundary. Refactored key endpoints to use streaming JSON decoding with json.NewDecoder, replacing less efficient parsing patterns and improving memory safety. Additionally, removed unnecessary body reads in the NotImplementedHandler to further reduce resource usage. The work demonstrated a strong focus on backend development, API security best practices, and efficient handling of HTTP request data in Go.
