This field is never accessed, except perhaps by dead code. It is likely that the field is simply vestigial, but it is also possible that the unused field points out a bug.

Risk Factors

  • Talk about the factors that make this vulnerability likely or unlikely to actually happen
  • Discuss the technical impact of a successful exploit of this vulnerability
  • Consider the likely [business impacts] of a successful attack


Example 1

The field named glue is not used in the following class. The author of the class has accidentally put quotes around the field name, transforming it into a string constant.

	public class Dead {
	  String glue;
	  public String getGlue() {
		return "glue";

Example 2

The field named glue is used in the following class, but only from a method that is never called.

	public class Dead {
	  String glue;
	  private String getGlue() {
		return glue;
