poutine

Created by BoostSecurity.io, poutine is a security scanner that detects misconfigurations and vulnerabilities in the build pipelines of a repository. It supports parsing CI workflows from GitHub Actions and Gitlab CI/CD. When given an access token with read-level access, poutine can analyze all the repositories of an organization to quickly gain insights into the security posture of the organization's software supply chain.

See the documentation for a list of rules currently supported by poutine.

Why poutine?

In French, the word "poutine", when not referring to the dish, can be used to mean "messy". Inspired by the complexity and intertwined dependencies of modern open-source projects, poutine reflects both a nod to our Montreal roots and the often messy, complex nature of securing software supply chains.

Usage

poutine [command] [arguments] [options]

Analyze a local repository

poutine analyze_local .

Analyze a remote GitHub repository

poutine analyze_repo org/repo --token "$GH_TOKEN"

Analyze all repositories in a GitHub organization

poutine analyze_org org --token "$GH_TOKEN"

Analyze all projects in a self-hosted Gitlab instance

poutine analyze_org my-org/project --token "$GL_TOKEN" --scm gitlab --scm-base-uri https://gitlab.example.com

Configuration Options

--token          SCM access token (required for the commands analyze_repo, analyze_org) (env: GH_TOKEN)
--format         Output format (default: pretty, json, sarif)
--ignore-forks   Ignore forked repositories in the organization(analyze_org)
--scm            SCM platform (default: github, gitlab)
--scm-base-uri   Base URI of the self-hosted SCM instance
--threads        Number of threads to use (default: 2)
--config         Path to the configuration file (default: .poutine.yml)
--verbose        Enable debug logging

For examples of vulnerabilities in GitHub Actions workflows, you can explore the Messy poutine GitHub organization. It showcases real-world vulnerabilities from open-source projects readily exploitable for educational purposes.

To get started with some hints, try using poutine to analyze the messypoutine organization:

poutine analyze_org messypoutine --token `gh auth token`
