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 setColorParams() throws Exception {
    assertPlotParam("bgcolor", "x000000");
    assertPlotParam("bgcolor", "XDEADBE");
    assertPlotParam("bgcolor", "%58DEADBE");
    assertInvalidPlotParam("bgcolor", "XDEADBEF");
    assertInvalidPlotParam("bgcolor", "%5BDEADBE");
    assertInvalidPlotParam("bgcolor", "xBDE%0AAD");

    assertPlotParam("fgcolor", "x000000");
    assertPlotParam("fgcolor", "XDEADBE");
    assertPlotParam("fgcolor", "%58DEADBE");
    assertInvalidPlotParam("fgcolor", "XDEADBEF");
    assertInvalidPlotParam("fgcolor", "%5BDEADBE");
    assertInvalidPlotParam("fgcolor", "xBDE%0AAD");
