security-diff-review

Automated security diff review works by analyzing code changes to identify regressions in authentication, input validation, and filesystem operations before they merge. It builds a narrow threat model for the affected sections and validates findings with code evidence.

A narrow threat model in diff analysis security focuses specifically on the altered code sections to identify targeted risks like tenant isolation or authorization flaws. This approach ensures security validation is backed by concrete evidence from the actual changes.

Review code changes for secrets and supply-chain vulnerabilities by executing the diff review script against your archive file. It automatically detects hardcoded secrets, dependency vulnerabilities, and CI/CD configuration risks while collecting evidence for remediation.

Yes, this security review tool validates findings by requiring concrete code evidence from the diff. If a potential security issue cannot be definitively linked to the code changes, it is explicitly marked as unvalidated to prevent false positives.

Yes, you can use diff analysis to check tenant isolation and authorization regressions by targeting these specific focus areas during the review. The analysis evaluates the modified code paths to ensure access controls remain strictly enforced.

The primary limitation of automated security diff review is its narrow scope, analyzing only the provided code changes rather than the entire codebase. Complex logic flaws or architectural vulnerabilities outside the immediate diff context may not be detected.
