This is the first in a series of blog posts examining the evolution of web app architecture over the past 10 years. This post examines the forces that have driven the architectural changes and a high-level view of a new architecture. In future posts, we’ll zoom in to details of specific parts of the system. The standard web application architecture suitable for many organizations has changed drastically in the past 10 years.

Over the past few weeks, Heroku proactively updated our entire Redis fleet with a version of Redis not vulnerable to CVE-2018-11218. This was an embargoed vulnerability, so we did this work without notifying our customers about the underlying cause. As always, our goal was to update all Heroku Redis instances well before the embargo expired. As a Data Infrastructure Engineer at Heroku, I wanted to share how we manage large fleet operations such as this one. The most important aspect of our job is keeping customers safe from security vulnerabilities, while also minimizing disruption and downtime. Those two objectives are…

All previously released versions of Sprockets, the software that powers the Rails asset pipeline, contain a directory traversal vulnerability. This vulnerability has been assigned CVE-2018-3760. How do I know if I'm affected? Rails applications are vulnerable if they have this setting enabled in their application: # config/environments/production.rb config.assets.compile = true # setting to true makes your app vulnerable Note: The default value of this setting that ships with Rails in production.rb is false. By default, Rails apps running in production mode are not vulnerable to this exploit. How do I fix it? To remediate this vulnerability, applications can either change…
