Important Security Update for IntelliJ IDEA 2016.1 and Older Versions
Today we have released IntelliJ IDEA 2016.1.2. In addition to the usual functionality fixes, this update addresses two important security issues.

It is strongly recommended for all users to install the update as soon as possible.
