NAME

snyk - CLI and build-time tool to find & fix known vulnerabilities in open-source dependencies

SYNOPSIS

snyk [COMMAND] [SUBCOMMAND] [OPTIONS] [PACKAGE] [-- COMPILER_OPTIONS]

DESCRIPTION

Snyk helps you find, fix and monitor known vulnerabilities in open-source dependencies.
For more information see https://snyk.io

Not sure where to start?

  1. authenticate with $ snyk auth
  2. test your local project with $ snyk test
  3. get alerted for new vulnerabilities with $ snyk monitor

COMMANDS

To see command-specific flags and usage, see help command, e.g. snyk container --help (available in Advanced Snyk Container CLI usage).

Available top-level CLI commands:

auth [API_TOKEN]
Authenticate Snyk CLI with a Snyk account
test
Test local project for vulnerabilities
monitor
Snapshot and continuously monitor your project
container
Test container images for vulnerabilities. See snyk container --help for full instructions.
iac
Find security issues in your Infrastructure as Code files. See snyk iac --help for full instructions.
config
Manage Snyk CLI configuration
protect
Applies the patches specified in your .snyk file to the local file system
policy
Display the .snyk policy for a package.
ignore
Modifies the .snyk policy to ignore stated issues
wizard
Configure your policy file to update, auto patch, and ignore vulnerabilities. Snyk wizard updates your .snyk file.

OPTIONS

To see command-specific flags and usage, see help command, e.g. snyk container --help. For advanced usage, we offer language and context-specific flags, listed further down this document.

--all-projects
(only in test and monitor commands) Auto-detect all projects in the working directory
--detection-depth=DEPTH
(only in test and monitor commands) Use with --all-projects or --yarn-workspaces to indicate how many subdirectories to search. DEPTH must be a number.

Default: 4 (the current working directory and 3 sub-directories)

--exclude=DIRECTORY[,DIRECTORY]...>
(only in test and monitor commands) Can be used with --all-projects and --yarn-workspaces to indicate sub-directories to exclude. Directories must be comma-separated.

If using with --detection-depth exclude ignores directories at any level deep.

--prune-repeated-subdependencies, -p
(only in test and monitor commands) Prune dependency trees, removing duplicate sub-dependencies. Will still find all vulnerabilities, but potentially not all of the vulnerable paths.
--print-deps
(only in test and monitor commands) Print the dependency tree before sending it for analysis.
--remote-repo-url=URL
Set or override the remote URL for the repository that you would like to monitor.
--dev
Include devDependencies.

Default: scan only production dependencies

--org=ORG_NAME
Specify the ORG_NAME to run Snyk commands tied to a specific organization. This will influence where will new projects be created after running monitor command, some features availability, and private test limits. If you have multiple organizations, you can set a default from the CLI using:

$ snyk config set org=ORG_NAME

Setting a default will ensure all newly monitored projects will be created under your default organization. If you need to override the default, you can use the --org=ORG_NAME argument.

Default: uses ORG_NAME that sets as default in your Account settings

--file=FILE
Sets a package file.

When testing locally or monitoring a project, you can specify the file that Snyk should inspect for package information. When omitted Snyk will try to detect the appropriate file for your project.

--ignore-policy
Ignores all set policies. The current policy in the .snyk file, Org level ignores and the project policy on snyk.io.
--trust-policies
Applies and uses ignore rules from your dependencies' Snyk policies, otherwise ignore policies are only shown as a suggestion.
--show-vulnerable-paths=none|some|all
Display the dependency paths from the top-level dependencies, down to the vulnerable packages. Doesn't affect output when using JSON --json output.

Default: some (a few example paths shown) false is an alias for none.

--project-name=PROJECT_NAME
Specify a custom Snyk project name.
--policy-path=PATH_TO_POLICY_FILE`
Manually pass a path to a Snyk policy file.
--json
Prints result in JSON format.
--json-file-output=OUTPUT_FILE_PATH
(only in test command) Save test output in JSON format directly to the specified file, regardless of whether or not you use the --json option. This is especially useful if you want to display the human-readable test output via stdout and at the same time save the JSON format output to a file.
--severity-threshold=low|medium|high|critical
Only report vulnerabilities of provided level or higher.
--fail-on=all|upgradable|patchable
Only fail when there are vulnerabilities that can be fixed.

all - fails when there is at least one vulnerability that can be either upgraded or patched.
upgradable - fails when there is at least one vulnerability that can be upgraded.
patchable - fails when there is at least one vulnerability that can be patched.

If vulnerabilities do not have a fix and this option is being used, tests will pass.

--dry-run
(only in protect command) Don't apply updates or patches during protect command run.
-- [COMPILER_OPTIONS]
Pass extra arguments directly to Gradle or Maven. E.g. snyk test -- --build-cache

Below are flags that are influencing CLI behavior for specific projects, languages, and contexts:

Maven options

--scan-all-unmanaged
Auto-detects maven jar, war, and aar files in a given directory.
Note: custom-built jar files, even with open source dependencies, are out of scope. 
--scan-unmanaged
Auto-detects maven jar, war, and aar files in a given directory, and individual testing can be done with --file=FILE_NAME
--reachable
(only in test and monitor commands) Analyze your source code to find which vulnerable functions and packages are called.
--reachable-timeout=TIMEOUT
The amount of time (in seconds) to wait for Snyk to gather reachability data. If it takes longer than TIMEOUT, Reachable Vulnerabilities are not reported. This does not affect regular test or monitor output.

Default: 300 (5 minutes).

Gradle options

More information about Gradle CLI options

--sub-project=NAME, --gradle-sub-project=NAME
For Gradle "multi-project" configurations, test a specific sub-project.
--all-sub-projects
For "multi-project" configurations, test all sub-projects.
--configuration-matching=CONFIGURATION_REGEX
Resolve dependencies using only configuration(s) that match the provided Java regular expression, e.g. ^releaseRuntimeClasspath$.
--configuration-attributes=ATTRIBUTE[,ATTRIBUTE]...
Select certain values of configuration attributes to resolve the dependencies. E.g. buildtype:release,usage:java-runtime

.Net & NuGet options

--assets-project-name
When monitoring a .NET project using NuGet PackageReference use the project name in project.assets.json, if found.
--packages-folder
Custom path to packages folder

npm options

--strict-out-of-sync=true|false

Default: true

Yarn options

--strict-out-of-sync=true|false

CocoaPods options

--strict-out-of-sync=true|false
Control testing out of sync lockfiles.

Default: false

Python options

--command=COMMAND
Indicate which specific Python commands to use based on the Python version. The default is python which executes your system's default python version. Run 'python -V' to find out what version is it. If you are using multiple Python versions, use this parameter to specify the correct Python command for execution.

Default: python Example: --command=python3

--skip-unresolved=true|false
Allow skipping packages that are not found in the environment.

$ snyk test
Test a specific dependency for vulnerabilities
$ snyk test ionic@1.6.5

More examples:

$ snyk test --show-vulnerable-paths=false

Container scanning

See snyk container --help for more details and examples:

$ snyk container test ubuntu:18.04 --org=my-team
$ snyk container test app:latest --file=Dockerfile --policy-path=path/to/.snyk

Infrastructure as Code (IAC) scanning

EXIT CODES

Possible exit codes and their meaning:

0: success, no vulns found
1: action_needed, vulns found
2: failure, try to re-run the command
3: failure, no supported projects detected

ENVIRONMENT

You can set these environment variables to change CLI run settings. These keys will override settings in your snyk config:

SNYK_TOKEN
Snyk authorization token. Setting this envvar will override the token that may be available in your snyk config settings.

How to get your account token
How to use Service Accounts

SNYK_API
Sets API host to use for Snyk requests. Useful for on-premise instances and configuring proxies.
SNYK_CFG_<KEY>
Allows you to override any key that's also available as snyk config option.

NOTICES

Snyk API usage policy

The use of Snyk's API, whether through the use of the 'snyk' npm package or otherwise, is subject to the terms & conditions
