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. The vulnerabilities, in various forms, are also present in older versions of the IDE; therefore, patches for those are also available. It is strongly recommended for all users to install the update as soon as possible.

Find more information about the vulnerabilities, the affected versions and ways to update in this special blog post:

UPDATE: If you’re running on OS X and the IDE doesn’t start after installing the update, please refer to for workarounds.

    IntelliJ 2016.x is the definition of complete mess.

    Gradle is completely broken. Updated to 2016.1.2 and it even more problems.

    I tried to remove my gradle modules and re-import them, now I am getting an error message “The project is already registered”. PLEASE TEST YOUR PRODUCT

      Mostafa, there were many changes in IntelliJ gradle integration.
      These changes have added the support for many gradle configurations(projects) that didn’t work in previous IntelliJ versions.
      However some gradle configurations were affected because of different workarounds usages and wrong assumptions in that projects.
      Most of such user requests were fixed in the 2016.1.x minor updates.

      If you discovered things that were working fine in the gradle integration of IntelliJ 15 but became broken in 2016.1.2, please file a bug to our issue tracker.
      And if it will be recognized as a regression bug, we will fix it asap with the highest priority.

    After the patch, indexing in IDEA became VERY slow with regards to scala plugin (I’m not sure if this matters though. I’m suspecting IDEA itself got slow). Indexing that would’ve took less than 10 seconds now takes a full minute.
