GitHub Security Lab

Discover the exciting world of cybersecurity research: what researchers do, essential skills, and actionable steps to begin your journey toward protecting the digital world.

Learn how specially crafted artifacts can be used to attack Maven repository managers. This post describes PoC exploits that can lead to pre-auth remote code execution and poisoning of the local artifacts in Sonatype Nexus and JFrog Artifactory.

In the last few months, we secured 75+ GitHub Actions workflows in open source projects, disclosing 90+ different vulnerabilities. Out of this research we produced new support for workflows in CodeQL, empowering you to secure yours.

We are excited to introduce the new CodeQL Community Packs, a comprehensive set of queries and models designed to enhance your code analysis capabilities. These packs are tailored to augment…

In this post, I’ll walk you through the vulnerabilities I uncovered in the GStreamer library and how I built a custom fuzzing generator to target MP4 files.

Learn how I discovered 11 new vulnerabilities by writing CodeQL models for Gradio framework and how you can do it, too.

Learn about browser extension security and secure your extensions with the help of CodeQL.

Vulnerability data has grown in volume and complexity over the past decade, but open source and programs like the Github Security Lab have helped supply chain security keep pace.

In this post, I’ll exploit CVE-2024-5830, a type confusion in Chrome that allows remote code execution (RCE) in the renderer sandbox of Chrome by a single visit to a malicious site.

In this blog post, we’ll explain how we discovered three critical vulnerabilities in Kafka UI and how they can be exploited.

In this post, I’ll exploit CVE-2024-3833, an object corruption bug in v8, the Javascript engine of Chrome, that allows remote code execution (RCE) in the renderer sandbox of Chrome by a single visit to a malicious site.

Can an attacker execute arbitrary commands on a remote server just by sending JSON? Yes, if the running code contains unsafe deserialization vulnerabilities. But how is that possible? In this blog post, we’ll describe how unsafe deserialization vulnerabilities work and how you can detect them in Ruby projects.

Learn how to use CodeQL for security research and improve your security research workflow.

This blog post is an in-depth walkthrough on how we perform security research leveraging GitHub features, including code scanning, CodeQL, and Codespaces.

In this post, I’ll look at CVE-2023-6241, a vulnerability in the Arm Mali GPU that allows a malicious app to gain arbitrary kernel code execution and root on an Android phone. I’ll show how this vulnerability can be exploited even when Memory Tagging Extension (MTE), a powerful mitigation, is enabled on the device.
