variant-analysis

Variant analysis identifies variants of known vulnerabilities across a codebase to detect related patterns. It generalizes a specific bug into broader detection queries to expand security coverage after an advisory.

Yes, you can use Semgrep and CodeQL for cross-language vulnerability detection. The variant analysis process utilizes these tools alongside ripgrep to detect related patterns across multiple files and repositories.

Pattern generalization in security audits is the process of expanding a known vulnerability into broader detection queries. This allows teams to hunt for related vulnerability variants across an entire codebase.

To generate reusable detection rules after an advisory, apply variant analysis to generalize the known vulnerability pattern. This creates persistent rules that you can roll into CI to prevent future regressions.

Yes, variant analysis works for cross-file and cross-language codebases. It leverages Semgrep, CodeQL, and ripgrep to effectively detect vulnerability variants and related patterns across different languages and files.

To prevent vulnerability regressions in CI, use variant analysis to create persistent detection rules from known bugs. Rolling these generalized rules into your continuous integration pipeline catches variants automatically.
