Method: Object#taint

Defined in:
object.c

#taint ⇒ Object

Mark the object as tainted.

Objects that are marked as tainted will be restricted from various built-in methods. This is to prevent insecure data, such as command-line arguments or strings read from Kernel#gets, from inadvertently compromising the users system.

To check whether an object is tainted, use #tainted?

You should only untaint a tainted object if your code has inspected it and determined that it is safe. To do so use #untaint

In $SAFE level 3, all newly created objects are tainted and you can’t untaint objects.

Returns:
