What is Safety DB?

Safety DB is a database of known security vulnerabilities in Python packages. The data is made available by and synced with this repository once per month. Most of the entries are found by filtering CVEs and changelogs for certain keywords and then manually reviewing them.


  • Safety CI is a deep GitHub integration that's available on It checks your commits and Pull Requests.
  • Safety is a command line tool that checks virtualenvironments and requirement files either locally or on a CI server.
