Java
Non-final 'clone()' in secure context
Warning
New
Last modified: 03 December 2024 Reports clone()
methods without the final
modifier.
Since clone()
can be used to instantiate objects without using a constructor, allowing the clone()
method to be overridden may result in corrupted objects, and even in security exploits. This may be prevented by making the clone()
method or the enclosing class itself final
.
Example:
class Main implements Cloneable {
@Override
protected Object clone() throws CloneNotSupportedException {
return super.clone();
}
}
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
