Sandboxed API Whitelist

compile-time-api-whitelist-block

Sandboxed .NET APIs get rejected by an enforced compile-time whitelist, so developers hit confusing build errors when importing standard namespaces; cross-environment exclusions (like Snyk scans) also diverge, making misapplied policies look like code issues.

the tests timeout — when using MSW + Testing Library + Tanstack Query. Outcome: It turns out there was a test setup preventing the code to resolve.

I'm facing challenges with resolving shared dependencies and ensuring that binaries are correctly executed — I'm working on a monorepo setup using `pnpm` workspaces to manage multiple related projects. Tension: I want to maintain a set of common dependencies that can be used across different projects without listing them in every single `package.json`. Outcome: You cannot share dependencies like this.

Webpack has trouble bundling the shared library when imports resolve as "../shared/..."

During `yarn build`, the Sentry sourcemap step fails with `One or more projects are invalid (http status: 400)`, shown as `error: API request failed`.

Errors from an ASP.NET Core 7 app are not appearing in Sentry, and the console shows `CSRF Verification Failed A required security token was not found or was invalid`.

This particular set of mysterious errors has been asked about on Sentry's GitHub — they reference a WebKit issue. Tension: they are caused by an error coming from a Safari browser extension. Outcome: can safely be ignored, or filtered.

Raw source code is being exposed through the Debugger Network tab via a `_N_E` server that serves per-page artifacts (likely source maps), including in production.

GitHub pull requests need approvals from both developer and QA teams, but built-in rulesets cannot enforce distinct-team approval order or identity

Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script. Tension: I didn't set any CSPs for my app.

I do not want to disable PowerShell monitoring entirely, nor globally allow AADInternals — in a hybrid environment using Azure AD Connect. Tension: Couldn’t find a way to trace or whitelist only that specific PowerShell import.

I need a way to sandbox the code and limit its permissions. — dynamically loading and executing third-party code. Outcome: there are (currently) no alternatives for running untrusted Java code within a Java application.

I have an ASP.NET Core 6.0 Web API. Tension: this issue is being flagged in the code if this library is no longer present. Outcome: Library: System.Formats.Asn1.

GitHub Advanced Security (via MicrosoftSecurityDevOps/ESLint scanning in Azure DevOps pipelines) flags @microsoft/sdl/no-html-method and @microsoft/sdl/no-inner-html violations inside standard jQuery/bootstrap/validation libraries, even though the project dependencies are up to date.

We run `dotnet list .sln package --vulnerable --include-transitive --source https://api.nuget.org/v3/index.json` nightly on our CI server. Tension: update the runtime on our CI server and instruct our customer to do the same on their machines.

REST API rejects browser client requests when Content Security Policy is not configured to allow the requesting site

snyk is only checking files ending with the .json, .yml, .txt etc. — I added my github projects to snyk.io portal to check vulnerabilities. Tension: It's not checking vulnerabilities in typescript, js, java, python files. Outcome: Then it should be under "Code Analysis" (second item in your screenshot).

Frontend and API subprojects need secure access control so unauthorized apps cannot use the API

Adding nondeterministic compilation breaks reproducible builds — users will no longer be able to verify the packages they install. Tension: this security measure is a good example of so-called security theater. Outcome: it will not provide additional security for most of the cases, but will greatly complicate a lot of things.

Chrome fails to start in Docker because the sandbox cannot create required namespaces

Snyk project scans do not consistently ignore/exclude folders depending on whether the project is imported via SCM versus run via the CLI, and behavior differs between Snyk Code (SAST) and Snyk Open Source scans.

dotnet tool install may resolve a package from NuGet.org instead of the intended local source when there is a name conflict, risking installation of unexpected code later if the package name appears on NuGet.

Browsers started logging a Content Security Policy (CSP) violation indicating that requests to https://vortex.data.microsoft.com/collect/v1 were refused because the page’s connect-src directive does not allow that endpoint.

Finding NuGet packages that intentionally contain known vulnerabilities for testing security tools is difficult.

Safari rejects the generated WebAssembly module with a CompileError: invalid extended GC op 24

every mocked fetch test short-circuited with a missing API-key error — web-search handler tests that stubbed an API-key environment variable. Tension: ESM imports are evaluated before the test's stub took effect.

Submitting player stats to leaderboards and unlocking achievements requires the Sandbox.Services API. — In s&box. Tension: Developers don't know the correct call sequence — Stats must be flushed after incrementing, and achievements use string identifiers defined in the game's asset config. Outcome: typos silently fail.

developers get confusing compile errors when trying to use System.IO, System.Reflection, System.Threading.Thread, System.Net, System.Diagnostics.Process, and other restricted APIs — In s&box, the .NET API is sandboxed. Tension: many standard .NET types and namespaces are blocked for security. Outcome: The whitelist is enforced at compile time.

WebSocket connections to external services use Sandbox.WebSocket, not System.Net.WebSockets (sandboxed out) — In s&box. Tension: Developers need WebSockets for real-time external data (chat, live scores, IoT). The same URL restrictions as Http apply — no IP addresses, HTTPS/WSS only.

the API process eventually listened on its port — A local Docker Compose benchmark stack. Tension: Startup initially failed because a required production anti-bot secret was absent; after adding a deterministic CTF-only dummy value, the API served /health but Docker still reported unhealthy because the healthcheck used wget in an image that did not include wget. Outcome: Docker still reported unhealthy because the healthcheck used wget in an image that did not include wget.

Chronicle package must sanitize prose writes through a privacy pipeline in a sibling package, but importing privacy directly couples tests, types, and reuse to the privacy package
