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 setSmoothParams() throws Exception {
    assertPlotParam("smooth", "unique");
    assertPlotParam("smooth", "frequency");
    assertPlotParam("smooth", "fnormal");
    assertPlotParam("smooth", "cumulative");
    assertPlotParam("smooth", "cnormal");
    assertPlotParam("smooth", "bins");
    assertPlotParam("smooth", "csplines");
    assertPlotParam("smooth", "acsplines");
    assertPlotParam("smooth", "mcsplines");
    assertPlotParam("smooth", "bezier");
    assertPlotParam("smooth", "sbezier");
    assertPlotParam("smooth", "unwrap");
    assertPlotParam("smooth", "zsort");
    assertInvalidPlotParam("smooth", "[33:system(%20");
