DESCRIPTION

cpan-audit is a command line application that checks the modules or distributions for known vulnerabilities. It is using its internal database that is automatically generated from a hand-picked database https://github.com/briandfoy/cpan-security-advisory.

cpan-audit does not connect to anything, that is why it is important to keep it up to date. Every update of the internal database is released as a new version. Ensure that you have the latest database by updating CPAN::Audit frequently; the database can change daily. You can use enable a warning for a possibly out-of-date database by adding --freshcheck, which warns if the database version is older than a month:

    % cpan-audit --freshcheck ...
    % cpan-audit -f ...

    % env CPAN_AUDIT_FRESH_DAYS=7 cpan-audit -f ...

Finding dependencies

cpan-audit can automatically detect dependencies from the following sources:

Carton

Parses cpanfile.snapshot file and checks the distribution versions.
cpanfile

Parses cpanfile taking into account the required versions.

It is assumed that if the required version of the module is less than a version of a release with a known vulnerability fix, then the module is considered affected.

Exit values

In prior versions, cpan-audit exited with the number of advisories it found. Starting with 1.001, if there are advisories found, cpan-audit exits with 64 added to that number.

0 - normal operation
2 - problem with program invocation, such as bad switches or values
64+n - advisories found. Subtract 64 to get the advisory count
