express-xss-sanitizer is a small, mature, widely-used Express middleware npm package (v2.0.2) that wraps sanitize-html to strip XSS payloads from req.body, req.query, req.headers and req.params. The code is compact, readable, and backed by a substantial mocha/supertest suite covering simple and nested objects, custom options, and route- vs app-level usage. The most material issue is that this security-critical package ships a production dependency (sanitize-html ~2.13.0) with a known MODERATE advisory (GHSA-vccv-cmxp-4j9h) for incomplete URI-scheme validation that can let javascript: URIs through certain attributes — directly relevant to a library whose whole purpose is XSS prevention. The two body-parser advisories are confined to devDependencies and are not shipped to consumers. Secondary concerns are in-place mutation of caller objects, sanitizing HTTP headers (unusual and potentially disruptive), and making req.query non-writable which can break downstream middleware. No hardcoded secrets were found. There is no novel IP at stake; this is a conventional sanitization wrapper. Overall the project is close to production-safe for its scope, conditional on bumping the sanitize-html dependency and validating the header/query behavior against downstream expectations.
