Common Weakness Enumeration

CWE-74 - Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
The software 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.
