Bandit

Bandit is an open-source static analysis security linter maintained by PyCQA that scans Python codebases to identify common security issues and coding practices that introduce vulnerabilities. It detects problems including use of unsafe functions, hardcoded passwords, SQL injection via string formatting, insecure cryptographic configurations, and subprocess shell injection risks through a plugin-based architecture with configurable severity and confidence levels. Python developers, security engineers, and DevSecOps teams integrate Bandit into CI/CD pipelines and pre-commit hooks to catch security issues during development before they reach code review or production. The tool provides clear, actionable output with CWE references and line-level findings, making it an essential component of secure Python development workflows alongside general-purpose linters like pylint and flake8.
