Description
The disclosed vulnerability allows a remote attacker to execute arbitrary JavaScript code.
The vulnerability exists due to insufficient sanitization of user-supplied data. The extend function does not restrict the modification of
an Object's prototype, which may allow an attacker to add or modify an
existing property that will exist on all objects. A remote attacker can inject and execute arbitrary script code.
