Heroku lets app developers spend their time on their application code, not managing servers, deployment, ongoing operations, or scaling. We are strong believers in free and open source software, and much of our code is available on our GitHub page. We are offering cash rewards on an ongoing basis for valid vulnerabilities, subject to the rules and terms of participation. The goal of this bounty is to find vulnerabilities which affect the confidentiality, integrity, or availability of our services and code run by us or our customers.
Before you begin, please read and understand the Standard Disclosure Terms. Heroku customer applications are out of scope for this program; you may only test against Heroku properties. You can identify public-facing Heroku properties by their EV SSL certificates; please see https://blog.heroku.com/fancy-pants-certs for additional information.
If you’re unsure about whether something is in-scope, please feel free to ask. With the exception of the listed out-of-scope findings, we base our severity and rewards on the Bugcrowd VRT.
Our main product and focus area for security, the platform itself is what all of the other targets support (and where most of them run).
Developers can create applications written in Ruby, Node.js, Java, Python, Clojure, Scala, Go, and PHP and deploy them on our platform. Once deployed, the application is assembled into a slug, which is then run on a dyno.
A dyno is a lightweight Linux container that runs a single user-specified command. A dyno can run any command available in its default environment (what we supply in the stack) or in your app’s slug (a compressed and pre-packaged copy of your application and its dependencies).

The platform API (
api.heroku.com) is how developers interact with the Heroku Platform. You can use the platform API to programmatically create apps, provision add-ons and perform other tasks.
Documentation: https://devcenter.heroku.com/articles/platform-api-reference and https://devcenter.heroku.com/categories/platform-api
The Heroku Dashboard is the web user interface for Heroku’s core features and functionality. This is the main web application target for our bounty.
It provides UI support for things like creating/renaming/deleting apps, configuring add-ons, managing Heroku Teams, creating Heroku Pipelines, deploying your application, viewing and responding to application metrics, and accessing usage, invoices and billing information.
Other Heroku products that are not part of the Heroku Dashboard can be accessed via the main navigation. Some of those products are Heroku Data, Dataclips, and Heroku Connect (Heroku/Salesforce Integration).
The Heroku Command Line Interface (CLI), formerly known as the Heroku Toolbelt, is a tool for creating and managing Heroku apps from the command line / shell of various operating systems. It is written in Go and Node and interacts with the Heroku Platform API.
Heroku CLI plugins that are published on Github under the Heroku org are also in scope and provide additional functionality to test (e.g. https://github.com/heroku/heroku-cli-addons).
Apache Kafka on Heroku
This is an expensive add-on and we do not have a free tier at this time for testing. However, we are interested in any vulnerabilities you may discover in Apache Kafka that are specific to our deployment.
Apache Kafka on Heroku is an add-on that provides Kafka as a service with full integration into the Heroku platform.
Apache Kafka is a distributed commit log for fast, fault-tolerant communication between producers and consumers using message based topics. Kafka provides the messaging backbone for building a new generation of distributed applications capable of handling billions of events and millions of transactions, and is designed to move large volumes of ephemeral data with a high degree of reliability and fault tolerance.
Heroku Connect is an add-on that synchronizes data between your Salesforce organization and a Heroku Postgres database. You can follow the getting started documentation to provision an application with Heroku Connect and use the free Demo plan for testing
Only the Heroku endpoints are in scope. Do not perform testing or attacks against any non-Heroku Salesforce URIs.
Documentation: https://www.heroku.com/connect and https://devcenter.heroku.com/articles/heroku-connect
Heroku recently added new features to their Postgres product, please read the blog post for full details. [As of 8/10/2017 at 12:30 PM PDT]
Additionally, at this time any vulnerability found within the new features will receive a 50% bonus. This bonus will be valid until 9/29/2017.
