Benchmark: Microsoft’s ESLint SDL security plugin catches XSS well, but misses most Node.js vuln classes
A benchmark-style analysis reports that Microsoft’s @microsoft/eslint-plugin-sdl detects DOM/XSS issues reliably but doesn’t cover many server-side Node.js vulnerability categories. The takeaway: match static analysis tools to your threat model.
A benchmark-style write-up evaluates **@microsoft/eslint-plugin-sdl** against a broader set of Node.js security test cases. **Reported result** - Detected 4/40 vulnerable patterns (~10%), but performed well on its focus area (DOM/XSS and code execution prevention). **Why it matters** Security plugins can create a false sense of coverage. Backend-heavy JavaScript apps still need checks for SSRF, injection, path traversal, weak crypto, and more. **Practical takeaway** Use the SDL ESLint plugin for DOM safety, but pair it with Node-focused rules, dependency scanning, and security review for server-side code. **Tags:** Web Development, Cyber Security, JavaScript, Node.js
