☕ Spring, ASP.NET, and Go Service Security Review Guide

Intro: Mature backend stacks still fail in repeatable ways: object-level authorization drift, insecure defaults around headers or proxies, weak admin separation, and unsafe operational endpoints. This guide compresses those risks into a reviewer-friendly format.

What this page includes

  • what to inspect in Spring-based services, ASP.NET Core services, and Go backends
  • practical authorization and operational-hardening questions
  • common mistakes that survive normal testing
  • release and review prompts

Shared focus areas across all three stacks

Reviewers should always inspect:

  • API-level authorization at the object and property level;
  • management or actuator-style endpoints;
  • proxy and forwarded-header trust;
  • deserialization and request-validation boundaries;
  • secret handling in config and logs;
  • outbound network trust and SSRF-prone helper code.

Spring-specific prompts

  • Are actuator endpoints scoped, authenticated, and intentionally exposed?
  • Is method-level or route-level authorization consistent with domain ownership checks?
  • Are management and application ports or contexts separated appropriately?

ASP.NET-specific prompts

  • Are antiforgery, cookie, and data-protection assumptions appropriate for the workload?
  • Are identity and policy mappings enforced server-side rather than inferred from UI role checks?
  • Are diagnostics, trace, and error pages disabled or constrained correctly?

Go-specific prompts

  • Do handlers validate and authorize per object, not just per route?
  • Are admin, debug, pprof, or metrics endpoints isolated correctly?
  • Are internal clients and metadata access paths constrained?
