Dustilock is a dependency vulnerability scanner that analyzes your dependencies for known security vulnerabilities and checks if there are newer, safer versions available. It scans various dependency files (package.json, requirements.txt, etc.) and provides alerts about vulnerable packages in your project, helping you maintain secure dependencies by identifying outdated packages with known CVEs.

Key Features:

  • Multi-Package Manager Support: Analyzes dependencies from npm, pip, composer, Maven, Gradle, and other popular package managers
  • Lock File Analysis: Deep inspection of lock files to identify exact vulnerable versions and transitive dependencies
  • Real-Time Vulnerability Database: Uses up-to-date vulnerability databases to detect the latest security issues
  • Supply Chain Security: Identifies compromised or malicious packages in the dependency tree
  • SARIF Output: Modern security report format for integration with development platforms and security tools
  • Detailed Reporting: Comprehensive reports with vulnerability details, severity scores, and remediation guidance
  • Version Upgrade Suggestions: Recommends safer, newer versions to resolve vulnerabilities
  • Transitive Dependency Analysis: Scans both direct and indirect dependencies for comprehensive coverage
  • Policy Enforcement: Configurable security policies to block builds with critical vulnerabilities

MegaLinter Flavors

Behind the scenes

How are identified applicable files

  • If this linter is active, all files will always be linted

How the linting is performed

dustilock is called once on the whole project directory (project CLI lint mode)

  • filtering can not be done using MegaLinter configuration variables,it must be done using dustilock configuration or ignore file (if existing)
  • VALIDATE_ALL_CODEBASE: false doesn't make dustilock analyze only updated files

Example calls
