CWE: CWE-74 \u2014 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.

Code:
  public void setKeyParams() throws Exception {
    assertPlotParam("key", "out");
    assertPlotParam("key", "left");
    assertPlotParam("key", "top");
    assertPlotParam("key", "center");
    assertPlotParam("key", "right");
    assertPlotParam("key", "horiz");
    assertPlotParam("key", "box");
    assertPlotParam("key", "bottom");
    assertInvalidPlotParam("yrange", "out%20right%20top%0aset%20yrange%20[33:system(%20");
  }
