On May 11th, Google Play released the Android Studio 2.1.1 update. This incremental update addresses a security vulnerability in the underlying IntelliJ platform that affects all previous versions of Android Studio. The vulnerability concerns the IDE itself and has no effect on individual apps.
Please update to Android Studio 2.1.1 as soon as possible. More information about the vulnerability can be found in this G+ posting.
To address this security vulnerability, simply go into Android Studio and check updates. For OS X users, navigate to the Android Studio Menu and click Check for Updates. For Windows or Linux users, navigate to the Help menu and clickCheck for Updates. You should be running at least Android Studio 2.1.1. The update message was sent as a in-product notification to all users of Android Studio. If you want a new install, you can download v2.1.1 from the Android Studio website.
If you’re still using v1.5.x and not able to switch to v2.x immediately, please download Android Studio v1.5.2 from the Android Studio tools website.
JetBrains has also released more details on the vulnerability.
Please read more on the issues and ways to update below.
Built-in web server vulnerabilities
The cross-site request forgery (CSRF) flaw in the IDE’s built-in webserver allowed an attacker to access local file system from a malicious web page without user consent.
Internal RPC vulnerabilities
Over-permissive CORS settings allowed attackers to use a malicious website in order to access various internal API endpoints, gain access to data saved by the IDE, and gather various meta-information like IDE version or open a project.
Our huge thanks go to Jordan Milne for disclosing these issues and working closely with us and to Android Studio team from Google for perfect collaboration while working on the fixes.
What to do
To install the update simply select ‘Check for Updates’ from inside the IDE or visitwww.jetbrains.com to download the most recent version. If you are using a version prior to 2016.1.x, read below for download links.

Q: Are earlier versions affected?
A: We are not aware of similar vulnerabilities in older versions. Built-in web server was introduced in December 2012 (branch 129.x), and the above-mentioned and fixed internal RPC vulnerabilities did not exist in older versions. Still, a possibility of vulnerabilities in older versions exists, which is why we recommend upgrading your IDE if it was released more than 3 years ago.
Q: What products are NOT affected?
A: ReSharper, ReSharper C++, dotCover, dotMemory, dotTrace, dotPeek, TeamCity, YouTrack, Upsource and Hub are not affected and do not need this security update.
Q: I need a full download rather than a patch for an earlier version of the IDE. Where can I download it?
A: Check the previous versions page for your product below. All versions published there contain the security update or are not affected by these two specific vulnerabilities.
- AppCode
- CLion
- DataGrip — please get the latest version from product website
- IntelliJ IDEA
