I conducted some research to try and identify YAML Injection issues in open-source projects using Snyk Code. Though the vulnerability itself is not a new one, the potential impact of YAML Injection is high, which made it a good candidate for research. This research led to the discovery of several issues in open-source projects written in Python, PHP and Ruby. This article focuses on the issue found in geokit-rails version 2.3.2, a plugin for Ruby on Rails
Were you tasked with building a product that requires the execution of dynamic JavaScript originating from end users? You might think building it on-top of Node.js VM module is a viable way to create a JavaScript sandbox. In this article, we’ll learn why that’s far from being a recommended approach and the security implications of doing so. Every now and then there’s a project that challenges the rudimentary and routine backend development. APIs? Message queues?
Mass assignment, also known as autobinding or object injection, is a category of vulnerabilities that occur when user input is bound to variables or objects within a program. Mass assignment vulnerabilities are often the result of an attacker adding unexpected fields to an object to manipulate the logic of a program.
I was inspired to write this after reading a post from Thomas Depierre on Mastodon. The post touched on something that’s been troubling me recently. When it comes to software security, we spend a lot of time talking about the software supply chain and related concepts, such as the software bill of materials (SBOM). This metaphor comes from an industrial lexicon. People who are used to talking about economies and how manufacturing works are familiar with the idea of supply chain.
If I throw a coin high up in the air, I know the outcome — it will either be heads or tails. However, I can’t predict which it will be. I will certainly be able to guess with a 50% chance, but I can’t be 100% certain. If I were to roll a die, my certainty becomes less (1 in 6). However, I still know what the output could be. Computers are great at many things, especially predictability. They are deterministic and creating a truly random number is impossible.
