While some browsers like recent versions of Chrome and Safari are able to block this type of attack, current versions of Firefox (and possibly others) do not. Mitigation: 1.x, 2.0.x, and 2.1.x users should upgrade to 2.1.3 or newer 2.2.x users should upgrade to 2.2.2 or newer 2.3.x users should upgrade to 2.3.1 or newer Credit: Spencer Gietzen, Rhino Security Labs References: https://spark.apache.org/security.html
