Jenkins Project

Jenkins is an open-source automation server whose vulnerability profile is shaped by its role as a widely deployed pipeline and CI/CD orchestration platform, with a large footprint spanning the core Jenkins server, plugin ecosystem (including Pipeline and Script Security), and integrations such as Active Directory authentication. The vendor's exposure recurs through application-layer weakness classes including cross-site scripting, cross-site request forgery, missing authorization checks, and insufficiently protected credentials—flaws characteristic of web-facing automation systems that interact with sensitive build artifacts and infrastructure secrets. A meaningful share of the vendor's disclosures reach serious severity, reflecting the elevated privilege and access scope that Jenkins often holds within development and deployment environments. Defenders should treat Jenkins deployments as trust-critical infrastructure, prioritize network isolation and access controls, and maintain close tracking of plugin updates alongside core server patches, since the extensible architecture means that third-party plugins frequently introduce new exposure vectors. Current severity, exploitation activity, and exposure counts are shown alongside this summary.
