Safety checks your installed dependencies for known security vulnerabilities.

By default it uses the open Python vulnerability database Safety DB, but can be upgraded to use pyup.io's Safety API using the --key option.

Installation

Install safety with pip

pip install safety

Usage

To check your currently selected virtual environment for dependencies with known security vulnerabilites, run:

safety check

You should get a report similar to this:

Now, let's install something insecure:

pip install insecure-package

Yeah, you can really install that.

Run safety check again:

Examples

Read requirement files

Just like pip, Safety is able to read local requirement files:

safety check -r requirements.txt

Read from stdin

Safety is also able to read from stdin with the --stdin flag set.

To check a local requirements file, run:

cat requirements.txt | safety check --stdin

or the output of pip freeze:

pip freeze | safety check --stdin

or to check a single package:

echo "insecure-package==0.1" | safety check --stdin

For more examples, take a look at the options section.

Using Safety with a CI service

Safety works great in your CI pipeline. It returns a non-zero exit status if it finds a vulnerability.

Run it before or after your tests. If Safety finds something, your tests will fail.

Travis

install:
  - pip install safety

script:
  - safety check

Deep GitHub Integration

If you are looking for a deep integration with your GitHub repositories: Safety is available as a part of pyup.io, called Safety CI. Safety CI checks your commits and pull requests for dependencies with known security vulnerabilities and displays a status on GitHub.

Using Safety in production

Safety is free and open source (MIT Licensed). The underlying open vulnerability database is updated once per month.

To get access to all vulnerabilites as soon as they are added, you need a Safety API key that comes with a paid pyup.io account, starting at $14.99 for individuals, or $49.99 for organizations.

Options

--key

API Key for pyup.io's vulnerability database. Can be set as SAFETY_API_KEY environment variable.

Example

safety check --key=12345-ABCDEFGH

---

--db

Path to a directory with a local vulnerability database including insecure.json and insecure_full.json

Example

safety check --db=/home/safety-db/data

---

--json

Output vulnerabilities in JSON format.

Example

safety check --json

[
    [
        "django",
        "<1.2.2",
        "1.2",
        "Cross-site scripting (XSS) vulnerability in Django 1.2.x before 1.2.2 allows remote attackers to inject arbitrary web script or HTML via a csrfmiddlewaretoken (aka csrf_token) cookie.",
        "25701"
    ]
]

---

--full-report

Full reports include a security advisory (if available).

Example

safety check --full-report
