My Research on Misconfigured Jenkins Servers

Late last year I decided to see how many misconfigured CI/CD (continuous integration and deployment) installations I could find on the internet. I decided to focus my research on one of the most popular CI/CD applications – Jenkins. This article isn’t an attack on Jenkins in any way shape or form – any piece of software and/or hardware can be configured incorrectly… it just so happens to be that CI/CD servers often host some very sensitive configurations – some of which I will come on to in a bit.
