In Nim before 1.2.6, the standard library asyncftpclient lacks a check for whether a message contains a newline character.

Weakness

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.
