SECURITY: Ensure _forum_session cookies cannot be reused between sites (stable) (#14949)
This only affects multisite Discourse instances (where multiple forums are served from a single application server). The vast majority of self-hosted Discourse forums do not fall into this category.

On affected instances, this vulnerability could allow encrypted session cookies to be re-used between sites served by the same application instance.

Development

To get your environment setup, follow the community setup guide for your operating system.

  1. If you're on macOS, try the macOS development guide.
  2. If you're on Ubuntu, try the Ubuntu development guide.
  3. If you're on Windows, try the Windows 10 development guide.

If you're familiar with how Rails works and are comfortable setting up your own environment, you can also try out the Discourse Advanced Developer Guide, which is aimed primarily at Ubuntu and macOS environments.

Before you get started, ensure you have the following minimum versions: Ruby 2.7+, PostgreSQL 13+, Redis 6.0+. If you're having trouble, please see our TROUBLESHOOTING GUIDE first!

If you're looking for business class hosting, see discourse.org/buy.

If you're looking for our remote work solution, see teams.discourse.com.

Built With

  • Ruby on Rails — Our back end API is a Rails app. It responds to requests RESTfully in JSON.
  • Ember.js — Our front end is an Ember.js app that communicates with the Rails API.
  • PostgreSQL — Our main data store is in Postgres.
  • Redis — We use Redis as a cache and for transient data.
  • BrowserStack — We use BrowserStack to test on real devices and browsers.

Plus lots of Ruby Gems, a complete list of which is at /master/Gemfile.
