Projects that are alternatives of or similar to Mix audit
MixAudit provides a mix deps.audit task to scan Mix dependencies for security vulnerabilities.
It draw its inspiration from tools like
npm audit and bundler-audit.
Installation
Project dependency
Add mix_audit to the deps function in your project’s mix.exs file:
defp deps do
[
{:mix_audit, "~> 0.1", only: [:dev, :test], runtime: false}
]
end
Then run mix do deps.get, deps.compile inside your project’s directory.
Local escript
If you do not wish to include mix_audit in your project dependencies, you can install it as global escript:
$ mix escript.install hex mix_audit
…
* creating …/.mix/escripts/mix_audit
The only difference is that instead of using the mix deps.audit task, you will have to use the created executable.
Usage
To generate a security report, you can use the deps.audit Mix task:
$ mix deps.audit
Options
| Option | Type | Default | Description |
|---|---|---|---|
--path |
String | Current directory | The root path of the project to audit |
--format |
String | "human" |
The format of the report to generate ("json" or "human") |
--ignore-advisory-ids |
String | "" |
Comma-separated list of advisory IDs to ignore |
--ignore-package-names |
String | "" |
Comma-separated list of package names to ignore |
Example
How does it work?
MixAudit builds two lists when it’s executed in a project:
- A list of security advisories fetched from the community-maintained
elixir-security-advisoriesrepository - A list of Mix dependencies from the various
mix.lockfiles in the project
Then, it loops through each project dependency and tries to find security advisories that apply to it (through its package name) and that match its version specification (through the advisory patched and unaffected version policies).
If one is found, a vulnerability (the combination of a security advisory and a project dependency) is then added to the report.
The task will exit with a 0 status only if the report passes (ie. it reports no vulnerabilities). Otherwise, it will exit with a 1 status.
