You already know that security is important to keep in mind when creating code and maintaining projects. Odds are, you also know that it’s much easier to think about security from the ground up rather than trying to squeeze it in at the end of a project.

But did you know that GitHub Actions injections are one of the most common vulnerabilities in projects stored in GitHub repositories? Thankfully, this is a relatively easy vulnerability to address, and GitHub has some tools to make it even easier.

From the 2024 Octoverse report detailing the most common types of OWASP-classified vulnerabilities identified by CodeQL in 2024. Our latest data shows a similar trend, highlighting the continued risks of injection attacks despite continued warnings for several decades.

Embracing a security mindset

The truth is that security is not something that is ever “done.” It’s a continuous process, one that you need to keep focusing on to help keep your code safe and secure. While automated tools are a huge help, they’re not an all-in-one, fire-and-forget solution.

This is why it’s important to understand the causes behind security vulnerabilities as well as how to address them. No tool will be 100% effective, but by increasing your understanding and deepening your knowledge, you will be better able to respond to threats. 

With that in mind, let’s talk about one of the most common vulnerabilities found in GitHub repositories.
