CWE: CWE-77 \u2014 Improper Neutralization of Special Elements used in a Command ('Command Injection')
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

Code:
  tag (cb) {
    assertVersionValid(this._version)
    const cmd = ['git', 'tag', 'v' + this._version].join(' ')
    exec(cmd, this._options, cb)
  }
