What is Jenkins Security vulnerabilities detected in Jenkins.

Understanding Jenkins

Jenkins is an open-source automation server that enables developers to build, test, and deploy their software reliably. It is widely used for continuous integration and continuous delivery (CI/CD) pipelines, allowing teams to automate the parts of software development related to building, testing, and deploying, facilitating continuous integration and continuous delivery.

Identifying the Symptom

One of the common issues encountered with Jenkins is security vulnerabilities. These vulnerabilities can manifest as unauthorized access, data breaches, or exploitation of Jenkins and its plugins. Users may observe warnings about potential security risks or receive alerts from security tools indicating vulnerabilities.
