## Schwachstellen-Klasse

- **CWE-74** — Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
  The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
