]| Parameter | Position | Path | Description | CWE |
|---|---|---|---|---|
| x[constructor][isBuffer] | query param | /?x[constructor][isBuffer]=y | An attacker can provide a nested query parameter that, when parsed by `qs.parse` (used by Express/body-parser) and subsequently re-serialized by `qs.stringify`, triggers a `TypeError` due to an unguarded duck-type check on the `isBuffer` property. | CWE-248, CWE-703 |
| a.constructor.isBuffer | request body | / | When `body-parser` with `extended: true` parses a JSON body containing a nested object with a `constructor` property and a non-callable `isBuffer` property, subsequent serialization using `qs.stringify` will cause a `TypeError` and potentially crash the process if not caught by an error boundary. | CWE-248, CWE-703 |
