Question 1

How do I ignore false positives in Sobelow?

Accepted Answer

Add # sobelow_skip comments before function definitions with module names (e.g., ["Traversal"]), or use the --ignore flag with comma-separated types. For bulk skipping, run --mark-skip-all to tag findings, then use --skip in future scans.

Question 2

Sobelow vs. Credo for Elixir security?

Accepted Answer

Sobelow is specialized for security vulnerability detection in Phoenix apps, while Credo is a general code linter for style and consistency. Use Sobelow for security audits and Credo for code quality, but they can complement each other in a pipeline.

Question 3

Does Sobelow work with Phoenix LiveView?

Accepted Answer

The README doesn't explicitly mention LiveView, but as it scans Phoenix code, it may detect related vulnerabilities. However, specific checks for LiveView patterns might be limited or require custom configuration.

Question 4

How to integrate Sobelow into CI/CD?

Accepted Answer

Use the --exit flag with a confidence threshold (e.g., --exit High) to return a non-zero exit status when findings are detected, allowing CI tools to fail builds. Combine with --format json for automated reporting.

Question 5

What vulnerabilities does Sobelow detect?

Accepted Answer

It covers issues like SQL injection, XSS, command injection, insecure configurations, and directory traversal, with a focus on Phoenix-specific patterns. The full list is in the modules section, accessible via mix help sobelow.

Question 6

Can Sobelow scan for vulnerable dependencies?

Accepted Answer

Yes, it includes checks for known-vulnerable dependencies as part of its modules, but it's not a replacement for dedicated dependency scanners like mix audit or Dependabot for comprehensive coverage.
