Discussion

Build-Scanner is a heuristic static analysis tool designed to automatically detect common high-impact web application vulnerabilities such as SQL/NoSQL injection, unsafe CORS, weak CSP, and missing CSRF protection in modern React/Node apps. It scans source code quickly without requiring live targets or sandbox environments and can be integrated into CI pipelines as a GitHub Action. The tool is intended to complement, not replace, full SAST/DAST tools and manual review. It flags risky code patterns in Express, Next.js, and Vite/CRA projects. Currently, it is in pre-release and shared for feedback, with no known exploits or patches applicable.

Modern React/Node apps ship through build pipelines fast enough that common, high-impact vulnerability classes — unparameterized queries, wildcard CORS, unsafe-inline CSP, unprotected state-changing routes — slip through because catching them means someone actually reading the source. build-scanner does that automatically: point it at a folder (or wire it into CI as a GitHub Action) and get a report in seconds, no sandbox or live target required. It's a heuristic static scanner, not a SAST/DAST replacement — I'm sharing it pre-release to get feedback from people running real Express/Next.js/Vite codebases before I cut a v1 tag. https://github.com/laxmipsarva/build-scanner

Impact

The tool itself does not represent a vulnerability but rather aids developers and security teams in identifying and mitigating common vulnerabilities before code reaches production. By enabling early detection of risky code patterns, it can reduce the likelihood of exploitable security flaws in web applications. There are no reported exploits or direct security impacts from the tool itself.

Defensive guidance

This is a security tool intended to improve vulnerability detection. Users should consider integrating Build-Scanner into their development and CI workflows to identify and address common security issues early. Since it is a heuristic scanner, findings should be reviewed carefully to confirm true positives. It complements but does not replace full static or dynamic application security testing and manual code review.

Summary

Build-Scanner is a heuristic, regex-based static source code scanner targeting common vulnerabilities in modern JavaScript web applications, including SQL and NoSQL injection, GraphQL misconfigurations, permissive CORS policies, unsafe Content Security Policy (CSP) settings, and missing CSRF protections. It operates by scanning source code folders or files and can be integrated into CI pipelines via a GitHub Action. The tool supports framework-aware detection for Express, Next.js, and Vite/CRA projects, identifying specific risky code patterns such as unparameterized queries, wildcard CORS origins, unsafe CSP directives, and unprotected state-changing routes. It is designed as a fast first-pass tool to catch common mistakes early in the development lifecycle, not as a full replacement for comprehensive security testing. The project is currently in pre-release with no official version 1.0 tag and no known exploits in the wild.
