pdm-audit-plugin 0.1.0

Default template for PDM package

pdm-audit

A PDM plugin that scans your Python project dependencies for known vulnerabilities. It leverages pip-audit to provide security auditing capabilities within your PDM workflow.

Features

• Multiple vulnerability data sources support
  • PyPI vulnerability database via the PyPI JSON API
  • OSV database support
• Multiple output formats:
  • Columnar (default)
  • JSON
  • Markdown
• Caching support with configurable time-to-live (TTL)
• Seamless integration with PDM's dependency management

Installation

pdm self add pdm-audit-plugin

Usage

Run pdm audit in your project directory:

pdm audit --help

Command Options

Options:
  -s, --service           The audit source. Default is PyPI, can be pypi, osv.
  -f, --format           The format to emit audit results in (choices: columns, json, markdown)
  --desc                 Include vulnerability descriptions (auto, on, off)
  --enable-cache         Enable the vulnerability query result cache
  --cache-ttl           The cache time-to-live in seconds (default: 1800)

Examples

Basic audit of project dependencies:

pdm audit

Using OSV as the vulnerability database:

pdm audit -s osv

Output in JSON format:

pdm audit -f json

Output in Markdown format:

pdm audit -f markdown

Disable caching:

pdm audit --enable-cache false

Customize cache TTL to 1 hour:

pdm audit --cache-ttl 3600

Security Model

This plugin inherits its security model from pip-audit. Please note:

• It identifies known vulnerabilities in your dependencies based on data from vulnerability databases
• It cannot detect undisclosed vulnerabilities or perform static code analysis
• The audit is only as accurate as the vulnerability data available in the chosen service (PyPI or OSV)

Cache Management

The plugin maintains a cache of vulnerability data to improve performance:

• Default cache location: .audit_cache in your project directory
• Default TTL: 1800 seconds (30 minutes)
• Cache can be disabled or customized via command options

Troubleshooting

Slow Audit Performance

• First-time audits may be slower due to cache population
• Subsequent audits will be faster if caching is enabled
• Consider adjusting cache TTL if needed

Connection Issues

If you encounter connection errors:

• Verify your internet connection
• Check if you're behind a corporate proxy
• Try switching between PyPI and OSV services
