# Bulkhead

Bulkhead is a library for SailJS that allows a developer to compartmentalize the functionality of their web application into individual service-oriented components.

Traditionally, MVC patterns tend to make developers stuff as much business logic into the controller...

However, this significantly reduces the extendability and scalability of a web application as business logic frequently needs to be accessed in an agnostic fashion.  (Web API, CLI, unit testing, reporting/mapReducing, cron, application components, etc.)

But with Bulkhead, developers can modularize services and NPM packages to perform a specific task and easily install it into a SailsJS project.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.
