EXPRESS-004Low severity-4 points

Body parser without a size limit

Part of Security, which counts for 30% of the overall score. When this check fires it deducts 4 points from that category, once per scan, no matter how many places it turns up.

What it detects

express.json / urlencoded / raw / text (or body-parser) is mounted without an explicit limit option, so it falls back to the default request-body cap.

Why it matters

A body parser mounted without an explicit limit uses the framework default, which may be larger than a given route needs and is easy to overlook. An oversized JSON or form body can tie up parsing and memory on endpoints that only ever expect a few kilobytes. Setting the limit per parser makes the accepted size a deliberate choice rather than an inherited default.

How to fix it

Pass an explicit limit to each parser, sized to the route: app.use(express.json({ limit: '10kb' })) and the same for urlencoded/raw/text. Set larger limits only on the specific upload or import routes that need them, mounted separately, and pair those with request validation.
